Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618370, here are decompositions:

31 + 8618339 = 8618370
41 + 8618329 = 8618370
43 + 8618327 = 8618370
53 + 8618317 = 8618370
73 + 8618297 = 8618370
83 + 8618287 = 8618370
97 + 8618273 = 8618370
113 + 8618257 = 8618370

Showing the first eight; more decompositions exist.
