Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167028, here are decompositions:
- 5 + 167023 = 167028
- 7 + 167021 = 167028
- 11 + 167017 = 167028
- 19 + 167009 = 167028
- 41 + 166987 = 167028
- 61 + 166967 = 167028
- 79 + 166949 = 167028
- 97 + 166931 = 167028
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 167,028 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 167028 first appears in π at position 789,209 of the decimal expansion (the 789,209ordinal-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.
