Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70440, here are decompositions:

11 + 70429 = 70440
17 + 70423 = 70440
47 + 70393 = 70440
59 + 70381 = 70440
61 + 70379 = 70440
67 + 70373 = 70440
89 + 70351 = 70440
113 + 70327 = 70440

Showing the first eight; more decompositions exist.
