Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689648, here are decompositions:

5 + 8689643 = 8689648
167 + 8689481 = 8689648
197 + 8689451 = 8689648
347 + 8689301 = 8689648
389 + 8689259 = 8689648
431 + 8689217 = 8689648
467 + 8689181 = 8689648
479 + 8689169 = 8689648

Showing the first eight; more decompositions exist.
