Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578180, here are decompositions:

61 + 33578119 = 33578180
73 + 33578107 = 33578180
241 + 33577939 = 33578180
271 + 33577909 = 33578180
463 + 33577717 = 33578180
607 + 33577573 = 33578180
751 + 33577429 = 33578180
859 + 33577321 = 33578180

Showing the first eight; more decompositions exist.
