Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70470, here are decompositions:

11 + 70459 = 70470
13 + 70457 = 70470
19 + 70451 = 70470
31 + 70439 = 70470
41 + 70429 = 70470
47 + 70423 = 70470
89 + 70381 = 70470
97 + 70373 = 70470

Showing the first eight; more decompositions exist.
