Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540296, here are decompositions:

79 + 31540217 = 31540296
83 + 31540213 = 31540296
89 + 31540207 = 31540296
107 + 31540189 = 31540296
149 + 31540147 = 31540296
173 + 31540123 = 31540296
197 + 31540099 = 31540296
233 + 31540063 = 31540296

Showing the first eight; more decompositions exist.

IPv4 address
