Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519792, here are decompositions:

23 + 31519769 = 31519792
89 + 31519703 = 31519792
113 + 31519679 = 31519792
131 + 31519661 = 31519792
191 + 31519601 = 31519792
389 + 31519403 = 31519792
503 + 31519289 = 31519792
593 + 31519199 = 31519792

Showing the first eight; more decompositions exist.
