Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731744, here are decompositions:

23 + 8731721 = 8731744
71 + 8731673 = 8731744
83 + 8731661 = 8731744
101 + 8731643 = 8731744
107 + 8731637 = 8731744
137 + 8731607 = 8731744
173 + 8731571 = 8731744
233 + 8731511 = 8731744

Showing the first eight; more decompositions exist.
