Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86784, here are decompositions:
- 13 + 86771 = 86784
- 17 + 86767 = 86784
- 31 + 86753 = 86784
- 41 + 86743 = 86784
- 73 + 86711 = 86784
- 107 + 86677 = 86784
- 157 + 86627 = 86784
- 197 + 86587 = 86784
Showing the first eight; more decompositions exist.
