Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491870, here are decompositions:

89 + 2147491781 = 2147491870
113 + 2147491757 = 2147491870
137 + 2147491733 = 2147491870
179 + 2147491691 = 2147491870
263 + 2147491607 = 2147491870
311 + 2147491559 = 2147491870
317 + 2147491553 = 2147491870
353 + 2147491517 = 2147491870

Showing the first eight; more decompositions exist.
