Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614170, here are decompositions:

37 + 31614133 = 31614170
61 + 31614109 = 31614170
73 + 31614097 = 31614170
79 + 31614091 = 31614170
109 + 31614061 = 31614170
151 + 31614019 = 31614170
163 + 31614007 = 31614170
331 + 31613839 = 31614170

Showing the first eight; more decompositions exist.
