Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618368, here are decompositions:

29 + 8618339 = 8618368
41 + 8618327 = 8618368
71 + 8618297 = 8618368
131 + 8618237 = 8618368
281 + 8618087 = 8618368
347 + 8618021 = 8618368
419 + 8617949 = 8618368
491 + 8617877 = 8618368

Showing the first eight; more decompositions exist.
