Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537952, here are decompositions:
- 13 + 31537939 = 31537952
- 31 + 31537921 = 31537952
- 109 + 31537843 = 31537952
- 211 + 31537741 = 31537952
- 349 + 31537603 = 31537952
- 379 + 31537573 = 31537952
- 409 + 31537543 = 31537952
- 613 + 31537339 = 31537952
Showing the first eight; more decompositions exist.
