Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742366, here are decompositions:

7 + 8742359 = 8742366
13 + 8742353 = 8742366
19 + 8742347 = 8742366
53 + 8742313 = 8742366
103 + 8742263 = 8742366
107 + 8742259 = 8742366
173 + 8742193 = 8742366
179 + 8742187 = 8742366

Showing the first eight; more decompositions exist.
