Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513494, here are decompositions:

71 + 31513423 = 31513494
83 + 31513411 = 31513494
163 + 31513331 = 31513494
191 + 31513303 = 31513494
281 + 31513213 = 31513494
293 + 31513201 = 31513494
307 + 31513187 = 31513494
347 + 31513147 = 31513494

Showing the first eight; more decompositions exist.
