Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523956, here are decompositions:

3 + 31523953 = 31523956
17 + 31523939 = 31523956
419 + 31523537 = 31523956
479 + 31523477 = 31523956
557 + 31523399 = 31523956
647 + 31523309 = 31523956
677 + 31523279 = 31523956
719 + 31523237 = 31523956

Showing the first eight; more decompositions exist.
