Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20974, here are decompositions:
- 11 + 20963 = 20974
- 53 + 20921 = 20974
- 71 + 20903 = 20974
- 101 + 20873 = 20974
- 167 + 20807 = 20974
- 227 + 20747 = 20974
- 257 + 20717 = 20974
- 281 + 20693 = 20974
Showing the first eight; more decompositions exist.

The digit sequence 20974 first appears in π at position 53 of the decimal expansion (the 53ordinal-suffix:rd 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.
