Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578072, here are decompositions:

61 + 33578011 = 33578072
139 + 33577933 = 33578072
163 + 33577909 = 33578072
181 + 33577891 = 33578072
421 + 33577651 = 33578072
499 + 33577573 = 33578072
571 + 33577501 = 33578072
613 + 33577459 = 33578072

Showing the first eight; more decompositions exist.
