Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42572, here are decompositions:

3 + 42569 = 42572
73 + 42499 = 42572
109 + 42463 = 42572
139 + 42433 = 42572
163 + 42409 = 42572
181 + 42391 = 42572
193 + 42379 = 42572
199 + 42373 = 42572

Showing the first eight; more decompositions exist.
