Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589750, here are decompositions:
- 13 + 31589737 = 31589750
- 19 + 31589731 = 31589750
- 43 + 31589707 = 31589750
- 67 + 31589683 = 31589750
- 139 + 31589611 = 31589750
- 211 + 31589539 = 31589750
- 277 + 31589473 = 31589750
- 349 + 31589401 = 31589750
Showing the first eight; more decompositions exist.
