Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732240, here are decompositions:

31 + 8732209 = 8732240
43 + 8732197 = 8732240
103 + 8732137 = 8732240
193 + 8732047 = 8732240
211 + 8732029 = 8732240
367 + 8731873 = 8732240
373 + 8731867 = 8732240
379 + 8731861 = 8732240

Showing the first eight; more decompositions exist.
