Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540804, here are decompositions:
- 17 + 31540787 = 31540804
- 167 + 31540637 = 31540804
- 173 + 31540631 = 31540804
- 311 + 31540493 = 31540804
- 461 + 31540343 = 31540804
- 563 + 31540241 = 31540804
- 587 + 31540217 = 31540804
- 593 + 31540211 = 31540804
Showing the first eight; more decompositions exist.
