Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490106, here are decompositions:

7 + 31490099 = 31490106
13 + 31490093 = 31490106
17 + 31490089 = 31490106
29 + 31490077 = 31490106
83 + 31490023 = 31490106
107 + 31489999 = 31490106
157 + 31489949 = 31490106
163 + 31489943 = 31490106

Showing the first eight; more decompositions exist.

IPv4 address
