Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461792, here are decompositions:

13 + 31461779 = 31461792
29 + 31461763 = 31461792
31 + 31461761 = 31461792
139 + 31461653 = 31461792
151 + 31461641 = 31461792
223 + 31461569 = 31461792
239 + 31461553 = 31461792
269 + 31461523 = 31461792

Showing the first eight; more decompositions exist.
