Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147583998, here are decompositions:

31 + 2147583967 = 2147583998
37 + 2147583961 = 2147583998
61 + 2147583937 = 2147583998
199 + 2147583799 = 2147583998
277 + 2147583721 = 2147583998
367 + 2147583631 = 2147583998
487 + 2147583511 = 2147583998
601 + 2147583397 = 2147583998

Showing the first eight; more decompositions exist.
