Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541352, here are decompositions:
- 5 + 31541347 = 31541352
- 71 + 31541281 = 31541352
- 83 + 31541269 = 31541352
- 109 + 31541243 = 31541352
- 173 + 31541179 = 31541352
- 179 + 31541173 = 31541352
- 191 + 31541161 = 31541352
- 211 + 31541141 = 31541352
Showing the first eight; more decompositions exist.
