Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146664, here are decompositions:
- 17 + 146647 = 146664
- 47 + 146617 = 146664
- 61 + 146603 = 146664
- 83 + 146581 = 146664
- 101 + 146563 = 146664
- 137 + 146527 = 146664
- 151 + 146513 = 146664
- 227 + 146437 = 146664
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 146,664 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 146664 first appears in π at position 374,091 of the decimal expansion (the 374,091ordinal-suffix:st 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.
