Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488994, here are decompositions:

127 + 2147488867 = 2147488994
421 + 2147488573 = 2147488994
577 + 2147488417 = 2147488994
613 + 2147488381 = 2147488994
661 + 2147488333 = 2147488994
823 + 2147488171 = 2147488994
883 + 2147488111 = 2147488994
967 + 2147488027 = 2147488994

Showing the first eight; more decompositions exist.
