Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489894, here are decompositions:

73 + 2147489821 = 2147489894
97 + 2147489797 = 2147489894
181 + 2147489713 = 2147489894
241 + 2147489653 = 2147489894
307 + 2147489587 = 2147489894
421 + 2147489473 = 2147489894
457 + 2147489437 = 2147489894
547 + 2147489347 = 2147489894

Showing the first eight; more decompositions exist.
