Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481676, here are decompositions:

53 + 31481623 = 31481676
67 + 31481609 = 31481676
167 + 31481509 = 31481676
179 + 31481497 = 31481676
197 + 31481479 = 31481676
199 + 31481477 = 31481676
223 + 31481453 = 31481676
227 + 31481449 = 31481676

Showing the first eight; more decompositions exist.
