Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732238, here are decompositions:

29 + 8732209 = 8732238
37 + 8732201 = 8732238
41 + 8732197 = 8732238
79 + 8732159 = 8732238
101 + 8732137 = 8732238
157 + 8732081 = 8732238
167 + 8732071 = 8732238
191 + 8732047 = 8732238

Showing the first eight; more decompositions exist.
