Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542572, here are decompositions:

5 + 33542567 = 33542572
83 + 33542489 = 33542572
233 + 33542339 = 33542572
251 + 33542321 = 33542572
311 + 33542261 = 33542572
353 + 33542219 = 33542572
383 + 33542189 = 33542572
419 + 33542153 = 33542572

Showing the first eight; more decompositions exist.
