Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614842, here are decompositions:

3 + 31614839 = 31614842
13 + 31614829 = 31614842
73 + 31614769 = 31614842
109 + 31614733 = 31614842
139 + 31614703 = 31614842
199 + 31614643 = 31614842
211 + 31614631 = 31614842
241 + 31614601 = 31614842

Showing the first eight; more decompositions exist.
