Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2272, here are decompositions:
- 3 + 2269 = 2272
- 5 + 2267 = 2272
- 29 + 2243 = 2272
- 59 + 2213 = 2272
- 131 + 2141 = 2272
- 173 + 2099 = 2272
- 191 + 2081 = 2272
- 233 + 2039 = 2272
Showing the first eight; more decompositions exist.

The digit sequence 2272 first appears in π at position 3,988 of the decimal expansion (the 3,988ordinal-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.
