Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533054, here are decompositions:

41 + 31533013 = 31533054
53 + 31533001 = 31533054
73 + 31532981 = 31533054
83 + 31532971 = 31533054
131 + 31532923 = 31533054
173 + 31532881 = 31533054
181 + 31532873 = 31533054
191 + 31532863 = 31533054

Showing the first eight; more decompositions exist.

IPv4 address
