Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147481136, here are decompositions:

83 + 2147481053 = 2147481136
167 + 2147480969 = 2147481136
179 + 2147480957 = 2147481136
239 + 2147480897 = 2147481136
293 + 2147480843 = 2147481136
389 + 2147480747 = 2147481136
617 + 2147480519 = 2147481136
677 + 2147480459 = 2147481136

Showing the first eight; more decompositions exist.

IPv4 address
