Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523704, here are decompositions:

53 + 31523651 = 31523704
71 + 31523633 = 31523704
167 + 31523537 = 31523704
227 + 31523477 = 31523704
263 + 31523441 = 31523704
293 + 31523411 = 31523704
461 + 31523243 = 31523704
467 + 31523237 = 31523704

Showing the first eight; more decompositions exist.
