Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523276, here are decompositions:

67 + 31523209 = 31523276
157 + 31523119 = 31523276
163 + 31523113 = 31523276
223 + 31523053 = 31523276
607 + 31522669 = 31523276
613 + 31522663 = 31523276
619 + 31522657 = 31523276
643 + 31522633 = 31523276

Showing the first eight; more decompositions exist.
