Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731764, here are decompositions:

7 + 8731757 = 8731764
43 + 8731721 = 8731764
53 + 8731711 = 8731764
103 + 8731661 = 8731764
127 + 8731637 = 8731764
137 + 8731627 = 8731764
157 + 8731607 = 8731764
193 + 8731571 = 8731764

Showing the first eight; more decompositions exist.
