Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493760, here are decompositions:

29 + 2147493731 = 2147493760
47 + 2147493713 = 2147493760
53 + 2147493707 = 2147493760
89 + 2147493671 = 2147493760
131 + 2147493629 = 2147493760
281 + 2147493479 = 2147493760
449 + 2147493311 = 2147493760
479 + 2147493281 = 2147493760

Showing the first eight; more decompositions exist.
