Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492882, here are decompositions:

23 + 31492859 = 31492882
41 + 31492841 = 31492882
101 + 31492781 = 31492882
131 + 31492751 = 31492882
191 + 31492691 = 31492882
353 + 31492529 = 31492882
389 + 31492493 = 31492882
461 + 31492421 = 31492882

Showing the first eight; more decompositions exist.
