Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495946, here are decompositions:

67 + 31495879 = 31495946
127 + 31495819 = 31495946
193 + 31495753 = 31495946
283 + 31495663 = 31495946
499 + 31495447 = 31495946
523 + 31495423 = 31495946
613 + 31495333 = 31495946
673 + 31495273 = 31495946

Showing the first eight; more decompositions exist.
