Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729618, here are decompositions:

61 + 8729557 = 8729618
127 + 8729491 = 8729618
151 + 8729467 = 8729618
229 + 8729389 = 8729618
379 + 8729239 = 8729618
397 + 8729221 = 8729618
439 + 8729179 = 8729618
487 + 8729131 = 8729618

Showing the first eight; more decompositions exist.
