Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544840, here are decompositions:
- 13 + 31544827 = 31544840
- 127 + 31544713 = 31544840
- 307 + 31544533 = 31544840
- 331 + 31544509 = 31544840
- 619 + 31544221 = 31544840
- 661 + 31544179 = 31544840
- 673 + 31544167 = 31544840
- 709 + 31544131 = 31544840
Showing the first eight; more decompositions exist.
