Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474826, here are decompositions:
- 43 + 31474783 = 31474826
- 79 + 31474747 = 31474826
- 139 + 31474687 = 31474826
- 157 + 31474669 = 31474826
- 277 + 31474549 = 31474826
- 307 + 31474519 = 31474826
- 337 + 31474489 = 31474826
- 463 + 31474363 = 31474826
Showing the first eight; more decompositions exist.
