Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493666, here are decompositions:

5 + 2147493661 = 2147493666
37 + 2147493629 = 2147493666
67 + 2147493599 = 2147493666
113 + 2147493553 = 2147493666
233 + 2147493433 = 2147493666
257 + 2147493409 = 2147493666
389 + 2147493277 = 2147493666
547 + 2147493119 = 2147493666

Showing the first eight; more decompositions exist.
