Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572800, here are decompositions:

59 + 33572741 = 33572800
101 + 33572699 = 33572800
113 + 33572687 = 33572800
263 + 33572537 = 33572800
311 + 33572489 = 33572800
353 + 33572447 = 33572800
383 + 33572417 = 33572800
419 + 33572381 = 33572800

Showing the first eight; more decompositions exist.
