Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761560, here are decompositions:

13 + 8761547 = 8761560
23 + 8761537 = 8761560
29 + 8761531 = 8761560
43 + 8761517 = 8761560
53 + 8761507 = 8761560
97 + 8761463 = 8761560
103 + 8761457 = 8761560
107 + 8761453 = 8761560

Showing the first eight; more decompositions exist.
