Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101564, here are decompositions:

3 + 101561 = 101564
31 + 101533 = 101564
37 + 101527 = 101564
61 + 101503 = 101564
97 + 101467 = 101564
181 + 101383 = 101564
223 + 101341 = 101564
241 + 101323 = 101564

Showing the first eight; more decompositions exist.
