Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712636, here are decompositions:

7 + 8712629 = 8712636
59 + 8712577 = 8712636
89 + 8712547 = 8712636
103 + 8712533 = 8712636
113 + 8712523 = 8712636
139 + 8712497 = 8712636
239 + 8712397 = 8712636
263 + 8712373 = 8712636

Showing the first eight; more decompositions exist.
