Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484844, here are decompositions:

23 + 2147484821 = 2147484844
53 + 2147484791 = 2147484844
227 + 2147484617 = 2147484844
233 + 2147484611 = 2147484844
317 + 2147484527 = 2147484844
353 + 2147484491 = 2147484844
383 + 2147484461 = 2147484844
467 + 2147484377 = 2147484844

Showing the first eight; more decompositions exist.
