Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732228, here are decompositions:

19 + 8732209 = 8732228
31 + 8732197 = 8732228
157 + 8732071 = 8732228
181 + 8732047 = 8732228
199 + 8732029 = 8732228
277 + 8731951 = 8732228
367 + 8731861 = 8732228
397 + 8731831 = 8732228

Showing the first eight; more decompositions exist.
