Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492738, here are decompositions:

37 + 2147492701 = 2147492738
67 + 2147492671 = 2147492738
199 + 2147492539 = 2147492738
211 + 2147492527 = 2147492738
367 + 2147492371 = 2147492738
409 + 2147492329 = 2147492738
421 + 2147492317 = 2147492738
439 + 2147492299 = 2147492738

Showing the first eight; more decompositions exist.
