Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732218, here are decompositions:

17 + 8732201 = 8732218
29 + 8732189 = 8732218
59 + 8732159 = 8732218
101 + 8732117 = 8732218
137 + 8732081 = 8732218
167 + 8732051 = 8732218
191 + 8732027 = 8732218
227 + 8731991 = 8732218

Showing the first eight; more decompositions exist.
