Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614978, here are decompositions:

37 + 31614941 = 31614978
79 + 31614899 = 31614978
89 + 31614889 = 31614978
97 + 31614881 = 31614978
127 + 31614851 = 31614978
139 + 31614839 = 31614978
149 + 31614829 = 31614978
181 + 31614797 = 31614978

Showing the first eight; more decompositions exist.
