Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480588, here are decompositions:

59 + 31480529 = 31480588
197 + 31480391 = 31480588
239 + 31480349 = 31480588
509 + 31480079 = 31480588
569 + 31480019 = 31480588
641 + 31479947 = 31480588
941 + 31479647 = 31480588
1031 + 31479557 = 31480588

Showing the first eight; more decompositions exist.
