Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491838, here are decompositions:

7 + 2147491831 = 2147491838
139 + 2147491699 = 2147491838
229 + 2147491609 = 2147491838
241 + 2147491597 = 2147491838
421 + 2147491417 = 2147491838
577 + 2147491261 = 2147491838
601 + 2147491237 = 2147491838
619 + 2147491219 = 2147491838

Showing the first eight; more decompositions exist.
