Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732148, here are decompositions:

11 + 8732137 = 8732148
31 + 8732117 = 8732148
67 + 8732081 = 8732148
97 + 8732051 = 8732148
101 + 8732047 = 8732148
157 + 8731991 = 8732148
167 + 8731981 = 8732148
197 + 8731951 = 8732148

Showing the first eight; more decompositions exist.
