Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601478, here are decompositions:

29 + 8601449 = 8601478
89 + 8601389 = 8601478
269 + 8601209 = 8601478
401 + 8601077 = 8601478
449 + 8601029 = 8601478
521 + 8600957 = 8601478
659 + 8600819 = 8601478
701 + 8600777 = 8601478

Showing the first eight; more decompositions exist.
