Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31521714, here are decompositions:
- 31 + 31521683 = 31521714
- 41 + 31521673 = 31521714
- 43 + 31521671 = 31521714
- 47 + 31521667 = 31521714
- 67 + 31521647 = 31521714
- 71 + 31521643 = 31521714
- 73 + 31521641 = 31521714
- 173 + 31521541 = 31521714
Showing the first eight; more decompositions exist.
