Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536132, here are decompositions:

31 + 31536101 = 31536132
71 + 31536061 = 31536132
79 + 31536053 = 31536132
83 + 31536049 = 31536132
113 + 31536019 = 31536132
149 + 31535983 = 31536132
151 + 31535981 = 31536132
191 + 31535941 = 31536132

Showing the first eight; more decompositions exist.

IPv4 address
