Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712642, here are decompositions:

13 + 8712629 = 8712642
31 + 8712611 = 8712642
41 + 8712601 = 8712642
109 + 8712533 = 8712642
151 + 8712491 = 8712642
269 + 8712373 = 8712642
271 + 8712371 = 8712642
293 + 8712349 = 8712642

Showing the first eight; more decompositions exist.
