Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537332, here are decompositions:
- 5 + 31537327 = 31537332
- 19 + 31537313 = 31537332
- 23 + 31537309 = 31537332
- 59 + 31537273 = 31537332
- 61 + 31537271 = 31537332
- 89 + 31537243 = 31537332
- 103 + 31537229 = 31537332
- 109 + 31537223 = 31537332
Showing the first eight; more decompositions exist.
