Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491462, here are decompositions:

59 + 2147491403 = 2147491462
101 + 2147491361 = 2147491462
113 + 2147491349 = 2147491462
239 + 2147491223 = 2147491462
269 + 2147491193 = 2147491462
401 + 2147491061 = 2147491462
419 + 2147491043 = 2147491462
443 + 2147491019 = 2147491462

Showing the first eight; more decompositions exist.

IPv4 address
