Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543192, here are decompositions:

11 + 31543181 = 31543192
29 + 31543163 = 31543192
59 + 31543133 = 31543192
89 + 31543103 = 31543192
113 + 31543079 = 31543192
173 + 31543019 = 31543192
251 + 31542941 = 31543192
281 + 31542911 = 31543192

Showing the first eight; more decompositions exist.
