Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564976, here are decompositions:
- 43 + 31564933 = 31564976
- 97 + 31564879 = 31564976
- 103 + 31564873 = 31564976
- 127 + 31564849 = 31564976
- 307 + 31564669 = 31564976
- 337 + 31564639 = 31564976
- 643 + 31564333 = 31564976
- 727 + 31564249 = 31564976
Showing the first eight; more decompositions exist.
