Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549814, here are decompositions:

13 + 31549801 = 31549814
61 + 31549753 = 31549814
97 + 31549717 = 31549814
151 + 31549663 = 31549814
223 + 31549591 = 31549814
433 + 31549381 = 31549814
487 + 31549327 = 31549814
577 + 31549237 = 31549814

Showing the first eight; more decompositions exist.
