Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486010, here are decompositions:

37 + 31485973 = 31486010
79 + 31485931 = 31486010
139 + 31485871 = 31486010
211 + 31485799 = 31486010
349 + 31485661 = 31486010
613 + 31485397 = 31486010
631 + 31485379 = 31486010
691 + 31485319 = 31486010

Showing the first eight; more decompositions exist.
