Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542602, here are decompositions:
- 43 + 31542559 = 31542602
- 79 + 31542523 = 31542602
- 163 + 31542439 = 31542602
- 211 + 31542391 = 31542602
- 229 + 31542373 = 31542602
- 373 + 31542229 = 31542602
- 439 + 31542163 = 31542602
- 499 + 31542103 = 31542602
Showing the first eight; more decompositions exist.
