Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528624, here are decompositions:
- 3 + 31528621 = 31528624
- 11 + 31528613 = 31528624
- 173 + 31528451 = 31528624
- 191 + 31528433 = 31528624
- 251 + 31528373 = 31528624
- 311 + 31528313 = 31528624
- 383 + 31528241 = 31528624
- 467 + 31528157 = 31528624
Showing the first eight; more decompositions exist.
