Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614838, here are decompositions:

5 + 31614833 = 31614838
41 + 31614797 = 31614838
131 + 31614707 = 31614838
137 + 31614701 = 31614838
191 + 31614647 = 31614838
197 + 31614641 = 31614838
251 + 31614587 = 31614838
389 + 31614449 = 31614838

Showing the first eight; more decompositions exist.
