Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2212, here are decompositions:

5 + 2207 = 2212
59 + 2153 = 2212
71 + 2141 = 2212
83 + 2129 = 2212
101 + 2111 = 2212
113 + 2099 = 2212
131 + 2081 = 2212
149 + 2063 = 2212

Showing the first eight; more decompositions exist.
