Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70212, here are decompositions:

5 + 70207 = 70212
11 + 70201 = 70212
13 + 70199 = 70212
29 + 70183 = 70212
31 + 70181 = 70212
71 + 70141 = 70212
73 + 70139 = 70212
89 + 70123 = 70212

Showing the first eight; more decompositions exist.
