Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540684, here are decompositions:
- 5 + 31540679 = 31540684
- 41 + 31540643 = 31540684
- 47 + 31540637 = 31540684
- 53 + 31540631 = 31540684
- 191 + 31540493 = 31540684
- 443 + 31540241 = 31540684
- 467 + 31540217 = 31540684
- 503 + 31540181 = 31540684
Showing the first eight; more decompositions exist.
