Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523716, here are decompositions:

47 + 31523669 = 31523716
83 + 31523633 = 31523716
137 + 31523579 = 31523716
179 + 31523537 = 31523716
239 + 31523477 = 31523716
317 + 31523399 = 31523716
449 + 31523267 = 31523716
479 + 31523237 = 31523716

Showing the first eight; more decompositions exist.
