Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530632, here are decompositions:

43 + 31530589 = 31530632
61 + 31530571 = 31530632
109 + 31530523 = 31530632
181 + 31530451 = 31530632
223 + 31530409 = 31530632
241 + 31530391 = 31530632
283 + 31530349 = 31530632
421 + 31530211 = 31530632

Showing the first eight; more decompositions exist.
