Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70542, here are decompositions:

5 + 70537 = 70542
13 + 70529 = 70542
41 + 70501 = 70542
53 + 70489 = 70542
61 + 70481 = 70542
83 + 70459 = 70542
103 + 70439 = 70542
113 + 70429 = 70542

Showing the first eight; more decompositions exist.
