Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294987660, here are decompositions:

53 + 4294987607 = 4294987660
71 + 4294987589 = 4294987660
137 + 4294987523 = 4294987660
233 + 4294987427 = 4294987660
503 + 4294987157 = 4294987660
599 + 4294987061 = 4294987660
701 + 4294986959 = 4294987660
797 + 4294986863 = 4294987660

Showing the first eight; more decompositions exist.
