Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577702, here are decompositions:
- 43 + 31577659 = 31577702
- 109 + 31577593 = 31577702
- 181 + 31577521 = 31577702
- 193 + 31577509 = 31577702
- 229 + 31577473 = 31577702
- 313 + 31577389 = 31577702
- 349 + 31577353 = 31577702
- 379 + 31577323 = 31577702
Showing the first eight; more decompositions exist.
