Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495104, here are decompositions:

41 + 31495063 = 31495104
61 + 31495043 = 31495104
101 + 31495003 = 31495104
167 + 31494937 = 31495104
181 + 31494923 = 31495104
197 + 31494907 = 31495104
337 + 31494767 = 31495104
367 + 31494737 = 31495104

Showing the first eight; more decompositions exist.
