Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539648, here are decompositions:
- 5 + 31539643 = 31539648
- 61 + 31539587 = 31539648
- 79 + 31539569 = 31539648
- 149 + 31539499 = 31539648
- 181 + 31539467 = 31539648
- 227 + 31539421 = 31539648
- 271 + 31539377 = 31539648
- 281 + 31539367 = 31539648
Showing the first eight; more decompositions exist.
