Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506792, here are decompositions:

11 + 31506781 = 31506792
43 + 31506749 = 31506792
73 + 31506719 = 31506792
103 + 31506689 = 31506792
151 + 31506641 = 31506792
193 + 31506599 = 31506792
223 + 31506569 = 31506792
263 + 31506529 = 31506792

Showing the first eight; more decompositions exist.
