Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549254, here are decompositions:

13 + 31549241 = 31549254
17 + 31549237 = 31549254
47 + 31549207 = 31549254
53 + 31549201 = 31549254
71 + 31549183 = 31549254
73 + 31549181 = 31549254
137 + 31549117 = 31549254
167 + 31549087 = 31549254

Showing the first eight; more decompositions exist.
