Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566792, here are decompositions:

29 + 31566763 = 31566792
43 + 31566749 = 31566792
79 + 31566713 = 31566792
83 + 31566709 = 31566792
181 + 31566611 = 31566792
193 + 31566599 = 31566792
233 + 31566559 = 31566792
251 + 31566541 = 31566792

Showing the first eight; more decompositions exist.
