Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462074, here are decompositions:

5 + 31462069 = 31462074
53 + 31462021 = 31462074
67 + 31462007 = 31462074
71 + 31462003 = 31462074
97 + 31461977 = 31462074
113 + 31461961 = 31462074
131 + 31461943 = 31462074
151 + 31461923 = 31462074

Showing the first eight; more decompositions exist.
