Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732272, here are decompositions:

11 + 8732261 = 8732272
71 + 8732201 = 8732272
83 + 8732189 = 8732272
113 + 8732159 = 8732272
149 + 8732123 = 8732272
179 + 8732093 = 8732272
191 + 8732081 = 8732272
281 + 8731991 = 8732272

Showing the first eight; more decompositions exist.
