Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490430, here are decompositions:

17 + 2147490413 = 2147490430
167 + 2147490263 = 2147490430
191 + 2147490239 = 2147490430
269 + 2147490161 = 2147490430
353 + 2147490077 = 2147490430
419 + 2147490011 = 2147490430
461 + 2147489969 = 2147490430
521 + 2147489909 = 2147490430

Showing the first eight; more decompositions exist.

IPv4 address
