Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637764, here are decompositions:

67 + 8637697 = 8637764
97 + 8637667 = 8637764
127 + 8637637 = 8637764
241 + 8637523 = 8637764
271 + 8637493 = 8637764
283 + 8637481 = 8637764
313 + 8637451 = 8637764
337 + 8637427 = 8637764

Showing the first eight; more decompositions exist.
