Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697388, here are decompositions:

149 + 8697239 = 8697388
281 + 8697107 = 8697388
389 + 8696999 = 8697388
449 + 8696939 = 8697388
521 + 8696867 = 8697388
599 + 8696789 = 8697388
677 + 8696711 = 8697388
761 + 8696627 = 8697388

Showing the first eight; more decompositions exist.
