Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101212, here are decompositions:

3 + 101209 = 101212
5 + 101207 = 101212
29 + 101183 = 101212
53 + 101159 = 101212
71 + 101141 = 101212
101 + 101111 = 101212
131 + 101081 = 101212
149 + 101063 = 101212

Showing the first eight; more decompositions exist.
