Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70642, here are decompositions:

3 + 70639 = 70642
23 + 70619 = 70642
53 + 70589 = 70642
59 + 70583 = 70642
71 + 70571 = 70642
113 + 70529 = 70642
191 + 70451 = 70642
263 + 70379 = 70642

Showing the first eight; more decompositions exist.
