Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492682, here are decompositions:

19 + 31492663 = 31492682
31 + 31492651 = 31492682
79 + 31492603 = 31492682
211 + 31492471 = 31492682
229 + 31492453 = 31492682
283 + 31492399 = 31492682
313 + 31492369 = 31492682
421 + 31492261 = 31492682

Showing the first eight; more decompositions exist.
