Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154664, here are decompositions:
- 43 + 154621 = 154664
- 73 + 154591 = 154664
- 163 + 154501 = 154664
- 241 + 154423 = 154664
- 277 + 154387 = 154664
- 313 + 154351 = 154664
- 331 + 154333 = 154664
- 373 + 154291 = 154664
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 154,664 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 154664 first appears in π at position 826,405 of the decimal expansion (the 826,405ordinal-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.
