Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70220, here are decompositions:

13 + 70207 = 70220
19 + 70201 = 70220
37 + 70183 = 70220
43 + 70177 = 70220
79 + 70141 = 70220
97 + 70123 = 70220
103 + 70117 = 70220
109 + 70111 = 70220

Showing the first eight; more decompositions exist.
