Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166624, here are decompositions:
- 5 + 166619 = 166624
- 11 + 166613 = 166624
- 23 + 166601 = 166624
- 53 + 166571 = 166624
- 83 + 166541 = 166624
- 137 + 166487 = 166624
- 167 + 166457 = 166624
- 467 + 166157 = 166624
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 166,624 and was likely granted around 1874.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 166624 first appears in π at position 227,353 of the decimal expansion (the 227,353ordinal-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.
