Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491902, here are decompositions:

5 + 2147491897 = 2147491902
71 + 2147491831 = 2147491902
211 + 2147491691 = 2147491902
293 + 2147491609 = 2147491902
349 + 2147491553 = 2147491902
359 + 2147491543 = 2147491902
499 + 2147491403 = 2147491902
541 + 2147491361 = 2147491902

Showing the first eight; more decompositions exist.

IPv4 address
