Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484886, here are decompositions:

17 + 2147484869 = 2147484886
269 + 2147484617 = 2147484886
317 + 2147484569 = 2147484886
359 + 2147484527 = 2147484886
509 + 2147484377 = 2147484886
647 + 2147484239 = 2147484886
653 + 2147484233 = 2147484886
683 + 2147484203 = 2147484886

Showing the first eight; more decompositions exist.

IPv4 address
