Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486076, here are decompositions:

43 + 31486033 = 31486076
67 + 31486009 = 31486076
103 + 31485973 = 31486076
277 + 31485799 = 31486076
757 + 31485319 = 31486076
829 + 31485247 = 31486076
883 + 31485193 = 31486076
997 + 31485079 = 31486076

Showing the first eight; more decompositions exist.
