Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72572, here are decompositions:

13 + 72559 = 72572
79 + 72493 = 72572
103 + 72469 = 72572
151 + 72421 = 72572
193 + 72379 = 72572
349 + 72223 = 72572
433 + 72139 = 72572
463 + 72109 = 72572

Showing the first eight; more decompositions exist.
