Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131682, here are decompositions:
- 11 + 131671 = 131682
- 41 + 131641 = 131682
- 43 + 131639 = 131682
- 71 + 131611 = 131682
- 101 + 131581 = 131682
- 139 + 131543 = 131682
- 163 + 131519 = 131682
- 181 + 131501 = 131682
Showing the first eight; more decompositions exist.
