Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614882, here are decompositions:

23 + 31614859 = 31614882
29 + 31614853 = 31614882
31 + 31614851 = 31614882
43 + 31614839 = 31614882
53 + 31614829 = 31614882
113 + 31614769 = 31614882
149 + 31614733 = 31614882
179 + 31614703 = 31614882

Showing the first eight; more decompositions exist.
