Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102664, here are decompositions:
- 11 + 102653 = 102664
- 17 + 102647 = 102664
- 53 + 102611 = 102664
- 71 + 102593 = 102664
- 101 + 102563 = 102664
- 113 + 102551 = 102664
- 131 + 102533 = 102664
- 167 + 102497 = 102664
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 102,664 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 102664 first appears in π at position 342,910 of the decimal expansion (the 342,910ordinal-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.
