Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42470, here are decompositions:

3 + 42467 = 42470
7 + 42463 = 42470
13 + 42457 = 42470
19 + 42451 = 42470
37 + 42433 = 42470
61 + 42409 = 42470
67 + 42403 = 42470
73 + 42397 = 42470

Showing the first eight; more decompositions exist.
