Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488786, here are decompositions:

59 + 2147488727 = 2147488786
167 + 2147488619 = 2147488786
173 + 2147488613 = 2147488786
227 + 2147488559 = 2147488786
269 + 2147488517 = 2147488786
479 + 2147488307 = 2147488786
719 + 2147488067 = 2147488786
743 + 2147488043 = 2147488786

Showing the first eight; more decompositions exist.
