Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690772, here are decompositions:

5 + 8690767 = 8690772
31 + 8690741 = 8690772
59 + 8690713 = 8690772
89 + 8690683 = 8690772
109 + 8690663 = 8690772
113 + 8690659 = 8690772
173 + 8690599 = 8690772
179 + 8690593 = 8690772

Showing the first eight; more decompositions exist.
