Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697928, here are decompositions:

59 + 8697869 = 8697928
131 + 8697797 = 8697928
137 + 8697791 = 8697928
149 + 8697779 = 8697928
251 + 8697677 = 8697928
347 + 8697581 = 8697928
389 + 8697539 = 8697928
419 + 8697509 = 8697928

Showing the first eight; more decompositions exist.
