Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571474, here are decompositions:
- 7 + 31571467 = 31571474
- 37 + 31571437 = 31571474
- 61 + 31571413 = 31571474
- 127 + 31571347 = 31571474
- 283 + 31571191 = 31571474
- 307 + 31571167 = 31571474
- 331 + 31571143 = 31571474
- 457 + 31571017 = 31571474
Showing the first eight; more decompositions exist.
