Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86464, here are decompositions:
- 3 + 86461 = 86464
- 11 + 86453 = 86464
- 23 + 86441 = 86464
- 41 + 86423 = 86464
- 83 + 86381 = 86464
- 107 + 86357 = 86464
- 113 + 86351 = 86464
- 167 + 86297 = 86464
Showing the first eight; more decompositions exist.
