Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530326, here are decompositions:

229 + 31530097 = 31530326
283 + 31530043 = 31530326
349 + 31529977 = 31530326
577 + 31529749 = 31530326
733 + 31529593 = 31530326
769 + 31529557 = 31530326
787 + 31529539 = 31530326
967 + 31529359 = 31530326

Showing the first eight; more decompositions exist.
