Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549484, here are decompositions:

73 + 31549411 = 31549484
103 + 31549381 = 31549484
157 + 31549327 = 31549484
277 + 31549207 = 31549484
283 + 31549201 = 31549484
367 + 31549117 = 31549484
397 + 31549087 = 31549484
433 + 31549051 = 31549484

Showing the first eight; more decompositions exist.
