Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70138, here are decompositions:

17 + 70121 = 70138
59 + 70079 = 70138
71 + 70067 = 70138
137 + 70001 = 70138
179 + 69959 = 70138
197 + 69941 = 70138
227 + 69911 = 70138
239 + 69899 = 70138

Showing the first eight; more decompositions exist.
