Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76564, here are decompositions:

3 + 76561 = 76564
23 + 76541 = 76564
53 + 76511 = 76564
71 + 76493 = 76564
83 + 76481 = 76564
101 + 76463 = 76564
197 + 76367 = 76564
281 + 76283 = 76564

Showing the first eight; more decompositions exist.
