Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537482, here are decompositions:
- 5 + 31537477 = 31537482
- 13 + 31537469 = 31537482
- 73 + 31537409 = 31537482
- 173 + 31537309 = 31537482
- 211 + 31537271 = 31537482
- 239 + 31537243 = 31537482
- 281 + 31537201 = 31537482
- 331 + 31537151 = 31537482
Showing the first eight; more decompositions exist.
