Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555788, here are decompositions:

31 + 33555757 = 33555788
37 + 33555751 = 33555788
61 + 33555727 = 33555788
109 + 33555679 = 33555788
127 + 33555661 = 33555788
271 + 33555517 = 33555788
307 + 33555481 = 33555788
349 + 33555439 = 33555788

Showing the first eight; more decompositions exist.
