Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614742, here are decompositions:

41 + 31614701 = 31614742
101 + 31614641 = 31614742
179 + 31614563 = 31614742
191 + 31614551 = 31614742
293 + 31614449 = 31614742
389 + 31614353 = 31614742
563 + 31614179 = 31614742
569 + 31614173 = 31614742

Showing the first eight; more decompositions exist.
