Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523914, here are decompositions:

113 + 31523801 = 31523914
263 + 31523651 = 31523914
281 + 31523633 = 31523914
503 + 31523411 = 31523914
647 + 31523267 = 31523914
677 + 31523237 = 31523914
683 + 31523231 = 31523914
887 + 31523027 = 31523914

Showing the first eight; more decompositions exist.
