Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614990, here are decompositions:

37 + 31614953 = 31614990
47 + 31614943 = 31614990
61 + 31614929 = 31614990
101 + 31614889 = 31614990
109 + 31614881 = 31614990
131 + 31614859 = 31614990
137 + 31614853 = 31614990
139 + 31614851 = 31614990

Showing the first eight; more decompositions exist.
