Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473258, here are decompositions:

17 + 2147473241 = 2147473258
41 + 2147473217 = 2147473258
71 + 2147473187 = 2147473258
107 + 2147473151 = 2147473258
131 + 2147473127 = 2147473258
137 + 2147473121 = 2147473258
197 + 2147473061 = 2147473258
461 + 2147472797 = 2147473258

Showing the first eight; more decompositions exist.

IPv4 address
