Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70538, here are decompositions:

31 + 70507 = 70538
37 + 70501 = 70538
79 + 70459 = 70538
109 + 70429 = 70538
157 + 70381 = 70538
211 + 70327 = 70538
229 + 70309 = 70538
241 + 70297 = 70538

Showing the first eight; more decompositions exist.
