Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529762, here are decompositions:

13 + 31529749 = 31529762
139 + 31529623 = 31529762
211 + 31529551 = 31529762
223 + 31529539 = 31529762
241 + 31529521 = 31529762
283 + 31529479 = 31529762
331 + 31529431 = 31529762
349 + 31529413 = 31529762

Showing the first eight; more decompositions exist.
