Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534178, here are decompositions:

37 + 31534141 = 31534178
61 + 31534117 = 31534178
127 + 31534051 = 31534178
199 + 31533979 = 31534178
211 + 31533967 = 31534178
229 + 31533949 = 31534178
307 + 31533871 = 31534178
331 + 31533847 = 31534178

Showing the first eight; more decompositions exist.
