Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615074, here are decompositions:

11 + 31615063 = 31615074
13 + 31615061 = 31615074
61 + 31615013 = 31615074
67 + 31615007 = 31615074
131 + 31614943 = 31615074
193 + 31614881 = 31615074
223 + 31614851 = 31615074
241 + 31614833 = 31615074

Showing the first eight; more decompositions exist.
