Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530462, here are decompositions:

11 + 31530451 = 31530462
43 + 31530419 = 31530462
53 + 31530409 = 31530462
71 + 31530391 = 31530462
79 + 31530383 = 31530462
113 + 31530349 = 31530462
151 + 31530311 = 31530462
193 + 31530269 = 31530462

Showing the first eight; more decompositions exist.
