Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537058, here are decompositions:

19 + 31537039 = 31537058
31 + 31537027 = 31537058
67 + 31536991 = 31537058
211 + 31536847 = 31537058
229 + 31536829 = 31537058
577 + 31536481 = 31537058
661 + 31536397 = 31537058
997 + 31536061 = 31537058

Showing the first eight; more decompositions exist.
