Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939664, here are decompositions:
- 3 + 939661 = 939664
- 41 + 939623 = 939664
- 53 + 939611 = 939664
- 83 + 939581 = 939664
- 113 + 939551 = 939664
- 233 + 939431 = 939664
- 251 + 939413 = 939664
- 317 + 939347 = 939664
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 939,664 and was likely granted around 1909.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 939664 first appears in π at position 20,449 of the decimal expansion (the 20,449ordinal-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.
