Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487906, here are decompositions:

7 + 2147487899 = 2147487906
37 + 2147487869 = 2147487906
73 + 2147487833 = 2147487906
79 + 2147487827 = 2147487906
89 + 2147487817 = 2147487906
103 + 2147487803 = 2147487906
107 + 2147487799 = 2147487906
127 + 2147487779 = 2147487906

Showing the first eight; more decompositions exist.

IPv4 address
