Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493660, here are decompositions:

31 + 2147493629 = 2147493660
43 + 2147493617 = 2147493660
61 + 2147493599 = 2147493660
71 + 2147493589 = 2147493660
107 + 2147493553 = 2147493660
113 + 2147493547 = 2147493660
181 + 2147493479 = 2147493660
227 + 2147493433 = 2147493660

Showing the first eight; more decompositions exist.

IPv4 address
