Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500084, here are decompositions:

37 + 31500047 = 31500084
61 + 31500023 = 31500084
67 + 31500017 = 31500084
151 + 31499933 = 31500084
163 + 31499921 = 31500084
191 + 31499893 = 31500084
241 + 31499843 = 31500084
251 + 31499833 = 31500084

Showing the first eight; more decompositions exist.
