Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2214, here are decompositions:

7 + 2207 = 2214
11 + 2203 = 2214
53 + 2161 = 2214
61 + 2153 = 2214
71 + 2143 = 2214
73 + 2141 = 2214
83 + 2131 = 2214
101 + 2113 = 2214

Showing the first eight; more decompositions exist.
