Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537760, here are decompositions:
- 13 + 31537747 = 31537760
- 19 + 31537741 = 31537760
- 43 + 31537717 = 31537760
- 73 + 31537687 = 31537760
- 151 + 31537609 = 31537760
- 157 + 31537603 = 31537760
- 283 + 31537477 = 31537760
- 421 + 31537339 = 31537760
Showing the first eight; more decompositions exist.
