Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537452, here are decompositions:
- 19 + 31537433 = 31537452
- 43 + 31537409 = 31537452
- 61 + 31537391 = 31537452
- 113 + 31537339 = 31537452
- 139 + 31537313 = 31537452
- 179 + 31537273 = 31537452
- 181 + 31537271 = 31537452
- 223 + 31537229 = 31537452
Showing the first eight; more decompositions exist.
