Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491502, here are decompositions:

229 + 2147491273 = 2147491502
241 + 2147491261 = 2147491502
283 + 2147491219 = 2147491502
379 + 2147491123 = 2147491502
421 + 2147491081 = 2147491502
433 + 2147491069 = 2147491502
619 + 2147490883 = 2147491502
631 + 2147490871 = 2147491502

Showing the first eight; more decompositions exist.

IPv4 address
