Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523694, here are decompositions:

43 + 31523651 = 31523694
47 + 31523647 = 31523694
61 + 31523633 = 31523694
157 + 31523537 = 31523694
173 + 31523521 = 31523694
227 + 31523467 = 31523694
233 + 31523461 = 31523694
283 + 31523411 = 31523694

Showing the first eight; more decompositions exist.
