Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572782, here are decompositions:

3 + 33572779 = 33572782
41 + 33572741 = 33572782
83 + 33572699 = 33572782
293 + 33572489 = 33572782
401 + 33572381 = 33572782
431 + 33572351 = 33572782
443 + 33572339 = 33572782
449 + 33572333 = 33572782

Showing the first eight; more decompositions exist.
