Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525462, here are decompositions:

41 + 31525421 = 31525462
83 + 31525379 = 31525462
131 + 31525331 = 31525462
173 + 31525289 = 31525462
179 + 31525283 = 31525462
233 + 31525229 = 31525462
251 + 31525211 = 31525462
359 + 31525103 = 31525462

Showing the first eight; more decompositions exist.
