Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463750, here are decompositions:
- 7 + 31463743 = 31463750
- 37 + 31463713 = 31463750
- 61 + 31463689 = 31463750
- 163 + 31463587 = 31463750
- 223 + 31463527 = 31463750
- 397 + 31463353 = 31463750
- 421 + 31463329 = 31463750
- 433 + 31463317 = 31463750
Showing the first eight; more decompositions exist.
