Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732420, here are decompositions:

3 + 8732417 = 8732420
163 + 8732257 = 8732420
181 + 8732239 = 8732420
211 + 8732209 = 8732420
223 + 8732197 = 8732420
283 + 8732137 = 8732420
349 + 8732071 = 8732420
373 + 8732047 = 8732420

Showing the first eight; more decompositions exist.
