Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742564, here are decompositions:

13 + 8742551 = 8742564
23 + 8742541 = 8742564
53 + 8742511 = 8742564
67 + 8742497 = 8742564
71 + 8742493 = 8742564
101 + 8742463 = 8742564
163 + 8742401 = 8742564
197 + 8742367 = 8742564

Showing the first eight; more decompositions exist.
