Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540914, here are decompositions:
- 43 + 31540871 = 31540914
- 47 + 31540867 = 31540914
- 101 + 31540813 = 31540914
- 127 + 31540787 = 31540914
- 131 + 31540783 = 31540914
- 191 + 31540723 = 31540914
- 257 + 31540657 = 31540914
- 263 + 31540651 = 31540914
Showing the first eight; more decompositions exist.
