Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534840, here are decompositions:
- 41 + 31534799 = 31534840
- 53 + 31534787 = 31534840
- 83 + 31534757 = 31534840
- 89 + 31534751 = 31534840
- 101 + 31534739 = 31534840
- 131 + 31534709 = 31534840
- 149 + 31534691 = 31534840
- 251 + 31534589 = 31534840
Showing the first eight; more decompositions exist.
