Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498780, here are decompositions:

13 + 2147498767 = 2147498780
43 + 2147498737 = 2147498780
103 + 2147498677 = 2147498780
127 + 2147498653 = 2147498780
151 + 2147498629 = 2147498780
199 + 2147498581 = 2147498780
331 + 2147498449 = 2147498780
367 + 2147498413 = 2147498780

Showing the first eight; more decompositions exist.
