Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497046, here are decompositions:
- 83 + 31496963 = 31497046
- 89 + 31496957 = 31497046
- 173 + 31496873 = 31497046
- 227 + 31496819 = 31497046
- 263 + 31496783 = 31497046
- 353 + 31496693 = 31497046
- 479 + 31496567 = 31497046
- 509 + 31496537 = 31497046
Showing the first eight; more decompositions exist.
