Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 964872, here are decompositions:
- 11 + 964861 = 964872
- 43 + 964829 = 964872
- 79 + 964793 = 964872
- 89 + 964783 = 964872
- 151 + 964721 = 964872
- 179 + 964693 = 964872
- 193 + 964679 = 964872
- 211 + 964661 = 964872
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 964,872 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 964872 first appears in π at position 728,451 of the decimal expansion (the 728,451ordinal-suffix:st 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.
