Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496004, here are decompositions:

83 + 31495921 = 31496004
107 + 31495897 = 31496004
157 + 31495847 = 31496004
251 + 31495753 = 31496004
263 + 31495741 = 31496004
271 + 31495733 = 31496004
311 + 31495693 = 31496004
313 + 31495691 = 31496004

Showing the first eight; more decompositions exist.
