Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537350, here are decompositions:
- 11 + 31537339 = 31537350
- 23 + 31537327 = 31537350
- 37 + 31537313 = 31537350
- 41 + 31537309 = 31537350
- 43 + 31537307 = 31537350
- 79 + 31537271 = 31537350
- 83 + 31537267 = 31537350
- 107 + 31537243 = 31537350
Showing the first eight; more decompositions exist.
