Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540936, here are decompositions:
- 113 + 31540823 = 31540936
- 149 + 31540787 = 31540936
- 227 + 31540709 = 31540936
- 257 + 31540679 = 31540936
- 293 + 31540643 = 31540936
- 443 + 31540493 = 31540936
- 593 + 31540343 = 31540936
- 719 + 31540217 = 31540936
Showing the first eight; more decompositions exist.
