Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618744, here are decompositions:

7 + 8618737 = 8618744
61 + 8618683 = 8618744
151 + 8618593 = 8618744
163 + 8618581 = 8618744
331 + 8618413 = 8618744
367 + 8618377 = 8618744
457 + 8618287 = 8618744
487 + 8618257 = 8618744

Showing the first eight; more decompositions exist.
