Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495324, here are decompositions:

83 + 31495241 = 31495324
137 + 31495187 = 31495324
167 + 31495157 = 31495324
281 + 31495043 = 31495324
401 + 31494923 = 31495324
557 + 31494767 = 31495324
587 + 31494737 = 31495324
617 + 31494707 = 31495324

Showing the first eight; more decompositions exist.
