Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496490, here are decompositions:

41 + 31496449 = 31496490
61 + 31496429 = 31496490
71 + 31496419 = 31496490
73 + 31496417 = 31496490
101 + 31496389 = 31496490
173 + 31496317 = 31496490
197 + 31496293 = 31496490
227 + 31496263 = 31496490

Showing the first eight; more decompositions exist.
