Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501558, here are decompositions:

79 + 2147501479 = 2147501558
127 + 2147501431 = 2147501558
337 + 2147501221 = 2147501558
457 + 2147501101 = 2147501558
571 + 2147500987 = 2147501558
577 + 2147500981 = 2147501558
967 + 2147500591 = 2147501558
997 + 2147500561 = 2147501558

Showing the first eight; more decompositions exist.
