Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541262, here are decompositions:

19 + 31541243 = 31541262
29 + 31541233 = 31541262
83 + 31541179 = 31541262
89 + 31541173 = 31541262
101 + 31541161 = 31541262
149 + 31541113 = 31541262
191 + 31541071 = 31541262
211 + 31541051 = 31541262

Showing the first eight; more decompositions exist.
