Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477274, here are decompositions:

61 + 31477213 = 31477274
67 + 31477207 = 31477274
163 + 31477111 = 31477274
211 + 31477063 = 31477274
223 + 31477051 = 31477274
421 + 31476853 = 31477274
541 + 31476733 = 31477274
547 + 31476727 = 31477274

Showing the first eight; more decompositions exist.
