Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467442, here are decompositions:

103 + 2147467339 = 2147467442
181 + 2147467261 = 2147467442
223 + 2147467219 = 2147467442
349 + 2147467093 = 2147467442
433 + 2147467009 = 2147467442
499 + 2147466943 = 2147467442
853 + 2147466589 = 2147467442
1123 + 2147466319 = 2147467442

Showing the first eight; more decompositions exist.
