Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614968, here are decompositions:

79 + 31614889 = 31614968
109 + 31614859 = 31614968
139 + 31614829 = 31614968
181 + 31614787 = 31614968
199 + 31614769 = 31614968
271 + 31614697 = 31614968
337 + 31614631 = 31614968
367 + 31614601 = 31614968

Showing the first eight; more decompositions exist.
