Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517576, here are decompositions:
- 3 + 31517573 = 31517576
- 19 + 31517557 = 31517576
- 43 + 31517533 = 31517576
- 109 + 31517467 = 31517576
- 163 + 31517413 = 31517576
- 379 + 31517197 = 31517576
- 757 + 31516819 = 31517576
- 787 + 31516789 = 31517576
Showing the first eight; more decompositions exist.
