Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537910, here are decompositions:
- 7 + 31537903 = 31537910
- 67 + 31537843 = 31537910
- 73 + 31537837 = 31537910
- 163 + 31537747 = 31537910
- 193 + 31537717 = 31537910
- 223 + 31537687 = 31537910
- 307 + 31537603 = 31537910
- 337 + 31537573 = 31537910
Showing the first eight; more decompositions exist.
