Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614872, here are decompositions:

13 + 31614859 = 31614872
19 + 31614853 = 31614872
43 + 31614829 = 31614872
103 + 31614769 = 31614872
139 + 31614733 = 31614872
229 + 31614643 = 31614872
241 + 31614631 = 31614872
271 + 31614601 = 31614872

Showing the first eight; more decompositions exist.
