Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492170, here are decompositions:

11 + 2147492159 = 2147492170
101 + 2147492069 = 2147492170
233 + 2147491937 = 2147492170
389 + 2147491781 = 2147492170
479 + 2147491691 = 2147492170
563 + 2147491607 = 2147492170
587 + 2147491583 = 2147492170
617 + 2147491553 = 2147492170

Showing the first eight; more decompositions exist.

IPv4 address
