Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541322, here are decompositions:

41 + 31541281 = 31541322
53 + 31541269 = 31541322
79 + 31541243 = 31541322
89 + 31541233 = 31541322
149 + 31541173 = 31541322
181 + 31541141 = 31541322
193 + 31541129 = 31541322
251 + 31541071 = 31541322

Showing the first eight; more decompositions exist.
