Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42440, here are decompositions:

3 + 42437 = 42440
7 + 42433 = 42440
31 + 42409 = 42440
37 + 42403 = 42440
43 + 42397 = 42440
61 + 42379 = 42440
67 + 42373 = 42440
103 + 42337 = 42440

Showing the first eight; more decompositions exist.
