Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476898, here are decompositions:

17 + 31476881 = 31476898
311 + 31476587 = 31476898
347 + 31476551 = 31476898
389 + 31476509 = 31476898
449 + 31476449 = 31476898
461 + 31476437 = 31476898
647 + 31476251 = 31476898
659 + 31476239 = 31476898

Showing the first eight; more decompositions exist.
