Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543034, here are decompositions:

43 + 31542991 = 31543034
67 + 31542967 = 31543034
97 + 31542937 = 31543034
157 + 31542877 = 31543034
223 + 31542811 = 31543034
307 + 31542727 = 31543034
331 + 31542703 = 31543034
337 + 31542697 = 31543034

Showing the first eight; more decompositions exist.
