Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476660, here are decompositions:

29 + 31476631 = 31476660
37 + 31476623 = 31476660
53 + 31476607 = 31476660
67 + 31476593 = 31476660
73 + 31476587 = 31476660
109 + 31476551 = 31476660
113 + 31476547 = 31476660
151 + 31476509 = 31476660

Showing the first eight; more decompositions exist.
