Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523896, here are decompositions:

227 + 31523669 = 31523896
263 + 31523633 = 31523896
317 + 31523579 = 31523896
359 + 31523537 = 31523896
419 + 31523477 = 31523896
587 + 31523309 = 31523896
617 + 31523279 = 31523896
653 + 31523243 = 31523896

Showing the first eight; more decompositions exist.
