Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646248, here are decompositions:

67 + 8646181 = 8646248
277 + 8645971 = 8646248
307 + 8645941 = 8646248
349 + 8645899 = 8646248
487 + 8645761 = 8646248
601 + 8645647 = 8646248
631 + 8645617 = 8646248
661 + 8645587 = 8646248

Showing the first eight; more decompositions exist.
