Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545792, here are decompositions:

29 + 31545763 = 31545792
43 + 31545749 = 31545792
53 + 31545739 = 31545792
79 + 31545713 = 31545792
151 + 31545641 = 31545792
163 + 31545629 = 31545792
181 + 31545611 = 31545792
193 + 31545599 = 31545792

Showing the first eight; more decompositions exist.
