Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656904, here are decompositions:

7 + 8656897 = 8656904
13 + 8656891 = 8656904
73 + 8656831 = 8656904
97 + 8656807 = 8656904
103 + 8656801 = 8656904
331 + 8656573 = 8656904
367 + 8656537 = 8656904
541 + 8656363 = 8656904

Showing the first eight; more decompositions exist.
