Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540850, here are decompositions:
- 13 + 31540837 = 31540850
- 37 + 31540813 = 31540850
- 67 + 31540783 = 31540850
- 127 + 31540723 = 31540850
- 151 + 31540699 = 31540850
- 157 + 31540693 = 31540850
- 181 + 31540669 = 31540850
- 193 + 31540657 = 31540850
Showing the first eight; more decompositions exist.
