Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495004, here are decompositions:

61 + 31494943 = 31495004
67 + 31494937 = 31495004
97 + 31494907 = 31495004
223 + 31494781 = 31495004
241 + 31494763 = 31495004
283 + 31494721 = 31495004
313 + 31494691 = 31495004
367 + 31494637 = 31495004

Showing the first eight; more decompositions exist.
