Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636772, here are decompositions:

13 + 8636759 = 8636772
31 + 8636741 = 8636772
59 + 8636713 = 8636772
71 + 8636701 = 8636772
83 + 8636689 = 8636772
101 + 8636671 = 8636772
139 + 8636633 = 8636772
173 + 8636599 = 8636772

Showing the first eight; more decompositions exist.
