Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513476, here are decompositions:

53 + 31513423 = 31513476
73 + 31513403 = 31513476
103 + 31513373 = 31513476
167 + 31513309 = 31513476
173 + 31513303 = 31513476
257 + 31513219 = 31513476
263 + 31513213 = 31513476
283 + 31513193 = 31513476

Showing the first eight; more decompositions exist.
