Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84572, here are decompositions:

13 + 84559 = 84572
73 + 84499 = 84572
109 + 84463 = 84572
151 + 84421 = 84572
181 + 84391 = 84572
223 + 84349 = 84572
349 + 84223 = 84572
373 + 84199 = 84572

Showing the first eight; more decompositions exist.
