Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2210, here are decompositions:

3 + 2207 = 2210
7 + 2203 = 2210
31 + 2179 = 2210
67 + 2143 = 2210
73 + 2137 = 2210
79 + 2131 = 2210
97 + 2113 = 2210
127 + 2083 = 2210

Showing the first eight; more decompositions exist.
