Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549694, here are decompositions:

3 + 31549691 = 31549694
31 + 31549663 = 31549694
97 + 31549597 = 31549694
103 + 31549591 = 31549694
283 + 31549411 = 31549694
313 + 31549381 = 31549694
367 + 31549327 = 31549694
457 + 31549237 = 31549694

Showing the first eight; more decompositions exist.
