Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618366, here are decompositions:

37 + 8618329 = 8618366
73 + 8618293 = 8618366
79 + 8618287 = 8618366
109 + 8618257 = 8618366
193 + 8618173 = 8618366
277 + 8618089 = 8618366
283 + 8618083 = 8618366
307 + 8618059 = 8618366

Showing the first eight; more decompositions exist.
