Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544012, here are decompositions:
- 109 + 31543903 = 31544012
- 139 + 31543873 = 31544012
- 229 + 31543783 = 31544012
- 433 + 31543579 = 31544012
- 523 + 31543489 = 31544012
- 739 + 31543273 = 31544012
- 769 + 31543243 = 31544012
- 1021 + 31542991 = 31544012
Showing the first eight; more decompositions exist.
