Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492082, here are decompositions:

3 + 31492079 = 31492082
31 + 31492051 = 31492082
241 + 31491841 = 31492082
421 + 31491661 = 31492082
463 + 31491619 = 31492082
571 + 31491511 = 31492082
613 + 31491469 = 31492082
751 + 31491331 = 31492082

Showing the first eight; more decompositions exist.
