Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539804, here are decompositions:
- 41 + 31539763 = 31539804
- 47 + 31539757 = 31539804
- 67 + 31539737 = 31539804
- 97 + 31539707 = 31539804
- 211 + 31539593 = 31539804
- 281 + 31539523 = 31539804
- 337 + 31539467 = 31539804
- 383 + 31539421 = 31539804
Showing the first eight; more decompositions exist.
