Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697866, here are decompositions:

7 + 8697859 = 8697866
43 + 8697823 = 8697866
97 + 8697769 = 8697866
367 + 8697499 = 8697866
433 + 8697433 = 8697866
487 + 8697379 = 8697866
523 + 8697343 = 8697866
613 + 8697253 = 8697866

Showing the first eight; more decompositions exist.
