Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70238, here are decompositions:

31 + 70207 = 70238
37 + 70201 = 70238
61 + 70177 = 70238
97 + 70141 = 70238
127 + 70111 = 70238
139 + 70099 = 70238
199 + 70039 = 70238
229 + 70009 = 70238

Showing the first eight; more decompositions exist.
