Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537326, here are decompositions:
- 13 + 31537313 = 31537326
- 17 + 31537309 = 31537326
- 19 + 31537307 = 31537326
- 53 + 31537273 = 31537326
- 59 + 31537267 = 31537326
- 83 + 31537243 = 31537326
- 97 + 31537229 = 31537326
- 103 + 31537223 = 31537326
Showing the first eight; more decompositions exist.
