Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560792, here are decompositions:

41 + 31560751 = 31560792
61 + 31560731 = 31560792
73 + 31560719 = 31560792
79 + 31560713 = 31560792
83 + 31560709 = 31560792
89 + 31560703 = 31560792
103 + 31560689 = 31560792
113 + 31560679 = 31560792

Showing the first eight; more decompositions exist.
