Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42488, here are decompositions:

31 + 42457 = 42488
37 + 42451 = 42488
79 + 42409 = 42488
97 + 42391 = 42488
109 + 42379 = 42488
139 + 42349 = 42488
151 + 42337 = 42488
157 + 42331 = 42488

Showing the first eight; more decompositions exist.
