Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495304, here are decompositions:

31 + 31495273 = 31495304
151 + 31495153 = 31495304
157 + 31495147 = 31495304
241 + 31495063 = 31495304
367 + 31494937 = 31495304
397 + 31494907 = 31495304
487 + 31494817 = 31495304
523 + 31494781 = 31495304

Showing the first eight; more decompositions exist.
