Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502, here are decompositions:
- 13 + 31489 = 31502
- 109 + 31393 = 31502
- 181 + 31321 = 31502
- 271 + 31231 = 31502
- 283 + 31219 = 31502
- 313 + 31189 = 31502
- 349 + 31153 = 31502
- 379 + 31123 = 31502
Showing the first eight; more decompositions exist.
