Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742636, here are decompositions:

13 + 8742623 = 8742636
59 + 8742577 = 8742636
107 + 8742529 = 8742636
137 + 8742499 = 8742636
139 + 8742497 = 8742636
167 + 8742469 = 8742636
173 + 8742463 = 8742636
257 + 8742379 = 8742636

Showing the first eight; more decompositions exist.
