Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537776, here are decompositions:
- 29 + 31537747 = 31537776
- 59 + 31537717 = 31537776
- 89 + 31537687 = 31537776
- 167 + 31537609 = 31537776
- 173 + 31537603 = 31537776
- 229 + 31537547 = 31537776
- 233 + 31537543 = 31537776
- 269 + 31537507 = 31537776
Showing the first eight; more decompositions exist.
