Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572878, here are decompositions:

29 + 33572849 = 33572878
137 + 33572741 = 33572878
179 + 33572699 = 33572878
191 + 33572687 = 33572878
389 + 33572489 = 33572878
431 + 33572447 = 33572878
461 + 33572417 = 33572878
569 + 33572309 = 33572878

Showing the first eight; more decompositions exist.
