Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86782, here are decompositions:
- 11 + 86771 = 86782
- 29 + 86753 = 86782
- 53 + 86729 = 86782
- 71 + 86711 = 86782
- 89 + 86693 = 86782
- 251 + 86531 = 86782
- 281 + 86501 = 86782
- 359 + 86423 = 86782
Showing the first eight; more decompositions exist.
