Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42512, here are decompositions:

3 + 42509 = 42512
13 + 42499 = 42512
61 + 42451 = 42512
79 + 42433 = 42512
103 + 42409 = 42512
109 + 42403 = 42512
139 + 42373 = 42512
163 + 42349 = 42512

Showing the first eight; more decompositions exist.
