Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576254, here are decompositions:

13 + 31576241 = 31576254
23 + 31576231 = 31576254
43 + 31576211 = 31576254
53 + 31576201 = 31576254
67 + 31576187 = 31576254
137 + 31576117 = 31576254
163 + 31576091 = 31576254
167 + 31576087 = 31576254

Showing the first eight; more decompositions exist.
