Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740564, here are decompositions:

3 + 8740561 = 8740564
5 + 8740559 = 8740564
23 + 8740541 = 8740564
47 + 8740517 = 8740564
71 + 8740493 = 8740564
137 + 8740427 = 8740564
191 + 8740373 = 8740564
197 + 8740367 = 8740564

Showing the first eight; more decompositions exist.
