Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42464, here are decompositions:
- 3 + 42461 = 42464
- 7 + 42457 = 42464
- 13 + 42451 = 42464
- 31 + 42433 = 42464
- 61 + 42403 = 42464
- 67 + 42397 = 42464
- 73 + 42391 = 42464
- 127 + 42337 = 42464
Showing the first eight; more decompositions exist.
