Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549692, here are decompositions:

29 + 31549663 = 31549692
43 + 31549649 = 31549692
101 + 31549591 = 31549692
103 + 31549589 = 31549692
113 + 31549579 = 31549692
131 + 31549561 = 31549692
193 + 31549499 = 31549692
241 + 31549451 = 31549692

Showing the first eight; more decompositions exist.
