Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474490, here are decompositions:
- 67 + 31474423 = 31474490
- 127 + 31474363 = 31474490
- 139 + 31474351 = 31474490
- 199 + 31474291 = 31474490
- 241 + 31474249 = 31474490
- 277 + 31474213 = 31474490
- 349 + 31474141 = 31474490
- 379 + 31474111 = 31474490
Showing the first eight; more decompositions exist.
