Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761564, here are decompositions:

17 + 8761547 = 8761564
47 + 8761517 = 8761564
101 + 8761463 = 8761564
107 + 8761457 = 8761564
131 + 8761433 = 8761564
311 + 8761253 = 8761564
431 + 8761133 = 8761564
557 + 8761007 = 8761564

Showing the first eight; more decompositions exist.
