Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456792, here are decompositions:

5 + 31456787 = 31456792
11 + 31456781 = 31456792
23 + 31456769 = 31456792
53 + 31456739 = 31456792
71 + 31456721 = 31456792
89 + 31456703 = 31456792
113 + 31456679 = 31456792
431 + 31456361 = 31456792

Showing the first eight; more decompositions exist.
