Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535162, here are decompositions:

19 + 31535143 = 31535162
31 + 31535131 = 31535162
79 + 31535083 = 31535162
103 + 31535059 = 31535162
151 + 31535011 = 31535162
163 + 31534999 = 31535162
181 + 31534981 = 31535162
283 + 31534879 = 31535162

Showing the first eight; more decompositions exist.

IPv4 address
