Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739642, here are decompositions:

5 + 8739637 = 8739642
19 + 8739623 = 8739642
59 + 8739583 = 8739642
113 + 8739529 = 8739642
139 + 8739503 = 8739642
151 + 8739491 = 8739642
179 + 8739463 = 8739642
211 + 8739431 = 8739642

Showing the first eight; more decompositions exist.
