Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70490, here are decompositions:

3 + 70487 = 70490
31 + 70459 = 70490
61 + 70429 = 70490
67 + 70423 = 70490
97 + 70393 = 70490
109 + 70381 = 70490
139 + 70351 = 70490
163 + 70327 = 70490

Showing the first eight; more decompositions exist.
