Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618624, here are decompositions:

31 + 8618593 = 8618624
43 + 8618581 = 8618624
67 + 8618557 = 8618624
181 + 8618443 = 8618624
211 + 8618413 = 8618624
307 + 8618317 = 8618624
331 + 8618293 = 8618624
337 + 8618287 = 8618624

Showing the first eight; more decompositions exist.
