Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70520, here are decompositions:

13 + 70507 = 70520
19 + 70501 = 70520
31 + 70489 = 70520
61 + 70459 = 70520
97 + 70423 = 70520
127 + 70393 = 70520
139 + 70381 = 70520
193 + 70327 = 70520

Showing the first eight; more decompositions exist.
