Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618376, here are decompositions:

37 + 8618339 = 8618376
47 + 8618329 = 8618376
59 + 8618317 = 8618376
79 + 8618297 = 8618376
83 + 8618293 = 8618376
89 + 8618287 = 8618376
103 + 8618273 = 8618376
139 + 8618237 = 8618376

Showing the first eight; more decompositions exist.
