Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523924, here are decompositions:

7 + 31523917 = 31523924
43 + 31523881 = 31523924
73 + 31523851 = 31523924
163 + 31523761 = 31523924
277 + 31523647 = 31523924
457 + 31523467 = 31523924
463 + 31523461 = 31523924
577 + 31523347 = 31523924

Showing the first eight; more decompositions exist.
