Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608792, here are decompositions:

13 + 31608779 = 31608792
43 + 31608749 = 31608792
71 + 31608721 = 31608792
79 + 31608713 = 31608792
263 + 31608529 = 31608792
311 + 31608481 = 31608792
443 + 31608349 = 31608792
491 + 31608301 = 31608792

Showing the first eight; more decompositions exist.
