Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534824, here are decompositions:
- 5 + 31534819 = 31534824
- 23 + 31534801 = 31534824
- 37 + 31534787 = 31534824
- 67 + 31534757 = 31534824
- 71 + 31534753 = 31534824
- 73 + 31534751 = 31534824
- 173 + 31534651 = 31534824
- 193 + 31534631 = 31534824
Showing the first eight; more decompositions exist.
