Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70640, here are decompositions:

13 + 70627 = 70640
19 + 70621 = 70640
67 + 70573 = 70640
103 + 70537 = 70640
139 + 70501 = 70640
151 + 70489 = 70640
181 + 70459 = 70640
211 + 70429 = 70640

Showing the first eight; more decompositions exist.
