Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497342, here are decompositions:

401 + 2147496941 = 2147497342
479 + 2147496863 = 2147497342
503 + 2147496839 = 2147497342
563 + 2147496779 = 2147497342
719 + 2147496623 = 2147497342
773 + 2147496569 = 2147497342
863 + 2147496479 = 2147497342
911 + 2147496431 = 2147497342

Showing the first eight; more decompositions exist.
