Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474646, here are decompositions:
- 97 + 31474549 = 31474646
- 127 + 31474519 = 31474646
- 157 + 31474489 = 31474646
- 223 + 31474423 = 31474646
- 283 + 31474363 = 31474646
- 397 + 31474249 = 31474646
- 433 + 31474213 = 31474646
- 613 + 31474033 = 31474646
Showing the first eight; more decompositions exist.
