Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493780, here are decompositions:

7 + 2147493773 = 2147493780
67 + 2147493713 = 2147493780
71 + 2147493709 = 2147493780
73 + 2147493707 = 2147493780
97 + 2147493683 = 2147493780
101 + 2147493679 = 2147493780
109 + 2147493671 = 2147493780
151 + 2147493629 = 2147493780

Showing the first eight; more decompositions exist.
