Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8606864, here are decompositions:

37 + 8606827 = 8606864
67 + 8606797 = 8606864
127 + 8606737 = 8606864
307 + 8606557 = 8606864
337 + 8606527 = 8606864
373 + 8606491 = 8606864
421 + 8606443 = 8606864
433 + 8606431 = 8606864

Showing the first eight; more decompositions exist.
