Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1674, here are decompositions:
- 5 + 1669 = 1674
- 7 + 1667 = 1674
- 11 + 1663 = 1674
- 17 + 1657 = 1674
- 37 + 1637 = 1674
- 47 + 1627 = 1674
- 53 + 1621 = 1674
- 61 + 1613 = 1674
Showing the first eight; more decompositions exist.

The digit sequence 1674 first appears in π at position 6,590 of the decimal expansion (the 6,590ordinal-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.
