Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697478, here are decompositions:

71 + 8697407 = 8697478
89 + 8697389 = 8697478
239 + 8697239 = 8697478
389 + 8697089 = 8697478
479 + 8696999 = 8697478
641 + 8696837 = 8697478
719 + 8696759 = 8697478
827 + 8696651 = 8697478

Showing the first eight; more decompositions exist.
