Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488486, here are decompositions:

179 + 2147488307 = 2147488486
239 + 2147488247 = 2147488486
419 + 2147488067 = 2147488486
443 + 2147488043 = 2147488486
587 + 2147487899 = 2147488486
617 + 2147487869 = 2147488486
653 + 2147487833 = 2147488486
659 + 2147487827 = 2147488486

Showing the first eight; more decompositions exist.

IPv4 address
