Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462118, here are decompositions:

97 + 31462021 = 31462118
139 + 31461979 = 31462118
157 + 31461961 = 31462118
199 + 31461919 = 31462118
277 + 31461841 = 31462118
307 + 31461811 = 31462118
421 + 31461697 = 31462118
547 + 31461571 = 31462118

Showing the first eight; more decompositions exist.
