Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523198, here are decompositions:

37 + 31523161 = 31523198
67 + 31523131 = 31523198
79 + 31523119 = 31523198
211 + 31522987 = 31523198
541 + 31522657 = 31523198
601 + 31522597 = 31523198
607 + 31522591 = 31523198
739 + 31522459 = 31523198

Showing the first eight; more decompositions exist.
