Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655474, here are decompositions:

17 + 8655457 = 8655474
41 + 8655433 = 8655474
53 + 8655421 = 8655474
71 + 8655403 = 8655474
73 + 8655401 = 8655474
103 + 8655371 = 8655474
131 + 8655343 = 8655474
167 + 8655307 = 8655474

Showing the first eight; more decompositions exist.
