Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33497780, here are decompositions:

3 + 33497777 = 33497780
7 + 33497773 = 33497780
109 + 33497671 = 33497780
157 + 33497623 = 33497780
331 + 33497449 = 33497780
367 + 33497413 = 33497780
439 + 33497341 = 33497780
499 + 33497281 = 33497780

Showing the first eight; more decompositions exist.
