Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615084, here are decompositions:

23 + 31615061 = 31615084
71 + 31615013 = 31615084
131 + 31614953 = 31615084
233 + 31614851 = 31615084
251 + 31614833 = 31615084
383 + 31614701 = 31615084
443 + 31614641 = 31615084
521 + 31614563 = 31615084

Showing the first eight; more decompositions exist.
