Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751564, here are decompositions:

7 + 8751557 = 8751564
37 + 8751527 = 8751564
61 + 8751503 = 8751564
71 + 8751493 = 8751564
97 + 8751467 = 8751564
103 + 8751461 = 8751564
113 + 8751451 = 8751564
137 + 8751427 = 8751564

Showing the first eight; more decompositions exist.
