Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732288, here are decompositions:

31 + 8732257 = 8732288
79 + 8732209 = 8732288
151 + 8732137 = 8732288
241 + 8732047 = 8732288
307 + 8731981 = 8732288
337 + 8731951 = 8732288
349 + 8731939 = 8732288
421 + 8731867 = 8732288

Showing the first eight; more decompositions exist.
