Goldbach decomposition

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.
