Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572890, here are decompositions:

41 + 33572849 = 33572890
149 + 33572741 = 33572890
191 + 33572699 = 33572890
353 + 33572537 = 33572890
401 + 33572489 = 33572890
443 + 33572447 = 33572890
509 + 33572381 = 33572890
557 + 33572333 = 33572890

Showing the first eight; more decompositions exist.
