Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577750, here are decompositions:
- 103 + 31577647 = 31577750
- 157 + 31577593 = 31577750
- 163 + 31577587 = 31577750
- 223 + 31577527 = 31577750
- 229 + 31577521 = 31577750
- 241 + 31577509 = 31577750
- 277 + 31577473 = 31577750
- 349 + 31577401 = 31577750
Showing the first eight; more decompositions exist.
