Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540112, here are decompositions:

3 + 31540109 = 31540112
13 + 31540099 = 31540112
103 + 31540009 = 31540112
181 + 31539931 = 31540112
211 + 31539901 = 31540112
223 + 31539889 = 31540112
349 + 31539763 = 31540112
463 + 31539649 = 31540112

Showing the first eight; more decompositions exist.

IPv4 address
