Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529444, here are decompositions:

13 + 31529431 = 31529444
31 + 31529413 = 31529444
97 + 31529347 = 31529444
277 + 31529167 = 31529444
337 + 31529107 = 31529444
601 + 31528843 = 31529444
613 + 31528831 = 31529444
631 + 31528813 = 31529444

Showing the first eight; more decompositions exist.
