Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614994, here are decompositions:

41 + 31614953 = 31614994
53 + 31614941 = 31614994
113 + 31614881 = 31614994
197 + 31614797 = 31614994
293 + 31614701 = 31614994
317 + 31614677 = 31614994
347 + 31614647 = 31614994
353 + 31614641 = 31614994

Showing the first eight; more decompositions exist.
