Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614230, here are decompositions:

3 + 31614227 = 31614230
13 + 31614217 = 31614230
19 + 31614211 = 31614230
31 + 31614199 = 31614230
97 + 31614133 = 31614230
139 + 31614091 = 31614230
211 + 31614019 = 31614230
223 + 31614007 = 31614230

Showing the first eight; more decompositions exist.
