Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70218, here are decompositions:

11 + 70207 = 70218
17 + 70201 = 70218
19 + 70199 = 70218
37 + 70181 = 70218
41 + 70177 = 70218
61 + 70157 = 70218
79 + 70139 = 70218
97 + 70121 = 70218

Showing the first eight; more decompositions exist.
