Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100664, here are decompositions:
- 43 + 100621 = 100664
- 73 + 100591 = 100664
- 127 + 100537 = 100664
- 163 + 100501 = 100664
- 181 + 100483 = 100664
- 271 + 100393 = 100664
- 307 + 100357 = 100664
- 331 + 100333 = 100664
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 100,664 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 100664 first appears in π at position 646,993 of the decimal expansion (the 646,993ordinal-suffix:rd 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.
