Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530760, here are decompositions:
- 47 + 31530713 = 31530760
- 59 + 31530701 = 31530760
- 101 + 31530659 = 31530760
- 167 + 31530593 = 31530760
- 263 + 31530497 = 31530760
- 281 + 31530479 = 31530760
- 383 + 31530377 = 31530760
- 419 + 31530341 = 31530760
Showing the first eight; more decompositions exist.
