Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460342, here are decompositions:

3 + 31460339 = 31460342
13 + 31460329 = 31460342
61 + 31460281 = 31460342
79 + 31460263 = 31460342
349 + 31459993 = 31460342
379 + 31459963 = 31460342
619 + 31459723 = 31460342
691 + 31459651 = 31460342

Showing the first eight; more decompositions exist.
