Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507572, here are decompositions:

31 + 33507541 = 33507572
193 + 33507379 = 33507572
313 + 33507259 = 33507572
349 + 33507223 = 33507572
463 + 33507109 = 33507572
751 + 33506821 = 33507572
883 + 33506689 = 33507572
991 + 33506581 = 33507572

Showing the first eight; more decompositions exist.
