Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712690, here are decompositions:

13 + 8712677 = 8712690
29 + 8712661 = 8712690
61 + 8712629 = 8712690
79 + 8712611 = 8712690
89 + 8712601 = 8712690
113 + 8712577 = 8712690
157 + 8712533 = 8712690
167 + 8712523 = 8712690

Showing the first eight; more decompositions exist.
