Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31487034, here are decompositions:

13 + 31487021 = 31487034
53 + 31486981 = 31487034
67 + 31486967 = 31487034
107 + 31486927 = 31487034
181 + 31486853 = 31487034
283 + 31486751 = 31487034
307 + 31486727 = 31487034
311 + 31486723 = 31487034

Showing the first eight; more decompositions exist.
