Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491262, here are decompositions:

13 + 2147491249 = 2147491262
43 + 2147491219 = 2147491262
61 + 2147491201 = 2147491262
139 + 2147491123 = 2147491262
151 + 2147491111 = 2147491262
181 + 2147491081 = 2147491262
193 + 2147491069 = 2147491262
229 + 2147491033 = 2147491262

Showing the first eight; more decompositions exist.

IPv4 address
