Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33512480, here are decompositions:

3 + 33512477 = 33512480
13 + 33512467 = 33512480
61 + 33512419 = 33512480
73 + 33512407 = 33512480
97 + 33512383 = 33512480
181 + 33512299 = 33512480
367 + 33512113 = 33512480
541 + 33511939 = 33512480

Showing the first eight; more decompositions exist.
