Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164730, here are decompositions:
- 23 + 164707 = 164730
- 29 + 164701 = 164730
- 47 + 164683 = 164730
- 53 + 164677 = 164730
- 67 + 164663 = 164730
- 103 + 164627 = 164730
- 107 + 164623 = 164730
- 109 + 164621 = 164730
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 164,730 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 164730 first appears in π at position 298,537 of the decimal expansion (the 298,537ordinal-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.
