Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489338, here are decompositions:

41 + 2147489297 = 2147489338
47 + 2147489291 = 2147489338
131 + 2147489207 = 2147489338
251 + 2147489087 = 2147489338
419 + 2147488919 = 2147489338
431 + 2147488907 = 2147489338
479 + 2147488859 = 2147489338
587 + 2147488751 = 2147489338

Showing the first eight; more decompositions exist.
