Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72564, here are decompositions:

5 + 72559 = 72564
13 + 72551 = 72564
17 + 72547 = 72564
31 + 72533 = 72564
61 + 72503 = 72564
67 + 72497 = 72564
71 + 72493 = 72564
83 + 72481 = 72564

Showing the first eight; more decompositions exist.
