Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42642, here are decompositions:

31 + 42611 = 42642
53 + 42589 = 42642
71 + 42571 = 42642
73 + 42569 = 42642
109 + 42533 = 42642
151 + 42491 = 42642
179 + 42463 = 42642
181 + 42461 = 42642

Showing the first eight; more decompositions exist.
