Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485100, here are decompositions:

3 + 2147485097 = 2147485100
43 + 2147485057 = 2147485100
109 + 2147484991 = 2147485100
139 + 2147484961 = 2147485100
151 + 2147484949 = 2147485100
181 + 2147484919 = 2147485100
223 + 2147484877 = 2147485100
349 + 2147484751 = 2147485100

Showing the first eight; more decompositions exist.

IPv4 address
