Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537376, here are decompositions:
- 37 + 31537339 = 31537376
- 67 + 31537309 = 31537376
- 103 + 31537273 = 31537376
- 109 + 31537267 = 31537376
- 223 + 31537153 = 31537376
- 229 + 31537147 = 31537376
- 337 + 31537039 = 31537376
- 349 + 31537027 = 31537376
Showing the first eight; more decompositions exist.
