Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999964, here are decompositions:
- 3 + 999961 = 999964
- 5 + 999959 = 999964
- 11 + 999953 = 999964
- 47 + 999917 = 999964
- 101 + 999863 = 999964
- 191 + 999773 = 999964
- 281 + 999683 = 999964
- 293 + 999671 = 999964
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 999,964 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 999964 first appears in π at position 220,569 of the decimal expansion (the 220,569ordinal-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.
