Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488830, here are decompositions:

37 + 2147488793 = 2147488830
79 + 2147488751 = 2147488830
89 + 2147488741 = 2147488830
103 + 2147488727 = 2147488830
139 + 2147488691 = 2147488830
211 + 2147488619 = 2147488830
251 + 2147488579 = 2147488830
257 + 2147488573 = 2147488830

Showing the first eight; more decompositions exist.
