Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530104, here are decompositions:

7 + 31530097 = 31530104
43 + 31530061 = 31530104
61 + 31530043 = 31530104
103 + 31530001 = 31530104
127 + 31529977 = 31530104
181 + 31529923 = 31530104
223 + 31529881 = 31530104
433 + 31529671 = 31530104

Showing the first eight; more decompositions exist.

IPv4 address
