Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621272, here are decompositions:

29 + 8621243 = 8621272
59 + 8621213 = 8621272
71 + 8621201 = 8621272
83 + 8621189 = 8621272
89 + 8621183 = 8621272
263 + 8621009 = 8621272
431 + 8620841 = 8621272
599 + 8620673 = 8621272

Showing the first eight; more decompositions exist.
