Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577850, here are decompositions:
- 37 + 31577813 = 31577850
- 53 + 31577797 = 31577850
- 67 + 31577783 = 31577850
- 71 + 31577779 = 31577850
- 181 + 31577669 = 31577850
- 191 + 31577659 = 31577850
- 193 + 31577657 = 31577850
- 257 + 31577593 = 31577850
Showing the first eight; more decompositions exist.
