Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501858, here are decompositions:

37 + 2147501821 = 2147501858
109 + 2147501749 = 2147501858
181 + 2147501677 = 2147501858
241 + 2147501617 = 2147501858
379 + 2147501479 = 2147501858
421 + 2147501437 = 2147501858
727 + 2147501131 = 2147501858
757 + 2147501101 = 2147501858

Showing the first eight; more decompositions exist.
