Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510058, here are decompositions:

37 + 31510021 = 31510058
67 + 31509991 = 31510058
109 + 31509949 = 31510058
241 + 31509817 = 31510058
277 + 31509781 = 31510058
367 + 31509691 = 31510058
397 + 31509661 = 31510058
457 + 31509601 = 31510058

Showing the first eight; more decompositions exist.
