Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614840, here are decompositions:

7 + 31614833 = 31614840
11 + 31614829 = 31614840
43 + 31614797 = 31614840
53 + 31614787 = 31614840
71 + 31614769 = 31614840
107 + 31614733 = 31614840
137 + 31614703 = 31614840
139 + 31614701 = 31614840

Showing the first eight; more decompositions exist.
