Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544518, here are decompositions:
- 101 + 31544417 = 31544518
- 311 + 31544207 = 31544518
- 347 + 31544171 = 31544518
- 419 + 31544099 = 31544518
- 461 + 31544057 = 31544518
- 479 + 31544039 = 31544518
- 521 + 31543997 = 31544518
- 557 + 31543961 = 31544518
Showing the first eight; more decompositions exist.
