Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519594, here are decompositions:

11 + 31519583 = 31519594
23 + 31519571 = 31519594
107 + 31519487 = 31519594
131 + 31519463 = 31519594
137 + 31519457 = 31519594
167 + 31519427 = 31519594
191 + 31519403 = 31519594
347 + 31519247 = 31519594

Showing the first eight; more decompositions exist.
