Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488228, here are decompositions:

167 + 2147488061 = 2147488228
227 + 2147488001 = 2147488228
359 + 2147487869 = 2147488228
401 + 2147487827 = 2147488228
449 + 2147487779 = 2147488228
617 + 2147487611 = 2147488228
719 + 2147487509 = 2147488228
827 + 2147487401 = 2147488228

Showing the first eight; more decompositions exist.

IPv4 address
