Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493476, here are decompositions:

19 + 2147493457 = 2147493476
43 + 2147493433 = 2147493476
67 + 2147493409 = 2147493476
199 + 2147493277 = 2147493476
307 + 2147493169 = 2147493476
367 + 2147493109 = 2147493476
397 + 2147493079 = 2147493476
433 + 2147493043 = 2147493476

Showing the first eight; more decompositions exist.
