Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523714, here are decompositions:

7 + 31523707 = 31523714
67 + 31523647 = 31523714
193 + 31523521 = 31523714
241 + 31523473 = 31523714
307 + 31523407 = 31523714
367 + 31523347 = 31523714
421 + 31523293 = 31523714
463 + 31523251 = 31523714

Showing the first eight; more decompositions exist.
