Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484646, here are decompositions:
- 19 + 31484627 = 31484646
- 29 + 31484617 = 31484646
- 103 + 31484543 = 31484646
- 113 + 31484533 = 31484646
- 197 + 31484449 = 31484646
- 229 + 31484417 = 31484646
- 233 + 31484413 = 31484646
- 269 + 31484377 = 31484646
Showing the first eight; more decompositions exist.
