Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 964820, here are decompositions:
- 37 + 964783 = 964820
- 67 + 964753 = 964820
- 127 + 964693 = 964820
- 211 + 964609 = 964820
- 313 + 964507 = 964820
- 397 + 964423 = 964820
- 457 + 964363 = 964820
- 463 + 964357 = 964820
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 964,820 and was likely granted around 1910.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 964820 first appears in π at position 404,417 of the decimal expansion (the 404,417ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
