Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529060, here are decompositions:

7 + 31529053 = 31529060
67 + 31528993 = 31529060
151 + 31528909 = 31529060
229 + 31528831 = 31529060
331 + 31528729 = 31529060
337 + 31528723 = 31529060
439 + 31528621 = 31529060
487 + 31528573 = 31529060

Showing the first eight; more decompositions exist.
