Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618360, here are decompositions:

31 + 8618329 = 8618360
43 + 8618317 = 8618360
67 + 8618293 = 8618360
73 + 8618287 = 8618360
103 + 8618257 = 8618360
109 + 8618251 = 8618360
139 + 8618221 = 8618360
211 + 8618149 = 8618360

Showing the first eight; more decompositions exist.
