Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523764, here are decompositions:

3 + 31523761 = 31523764
11 + 31523753 = 31523764
113 + 31523651 = 31523764
131 + 31523633 = 31523764
227 + 31523537 = 31523764
353 + 31523411 = 31523764
383 + 31523381 = 31523764
521 + 31523243 = 31523764

Showing the first eight; more decompositions exist.
