Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621180, here are decompositions:

7 + 33621173 = 33621180
11 + 33621169 = 33621180
17 + 33621163 = 33621180
31 + 33621149 = 33621180
67 + 33621113 = 33621180
71 + 33621109 = 33621180
97 + 33621083 = 33621180
113 + 33621067 = 33621180

Showing the first eight; more decompositions exist.

IPv4 address
