Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501618, here are decompositions:

7 + 2147501611 = 2147501618
139 + 2147501479 = 2147501618
181 + 2147501437 = 2147501618
397 + 2147501221 = 2147501618
487 + 2147501131 = 2147501618
541 + 2147501077 = 2147501618
631 + 2147500987 = 2147501618
709 + 2147500909 = 2147501618

Showing the first eight; more decompositions exist.
