Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534190, here are decompositions:

3 + 31534187 = 31534190
7 + 31534183 = 31534190
73 + 31534117 = 31534190
139 + 31534051 = 31534190
157 + 31534033 = 31534190
211 + 31533979 = 31534190
223 + 31533967 = 31534190
241 + 31533949 = 31534190

Showing the first eight; more decompositions exist.
