Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33577578, here are decompositions:

5 + 33577573 = 33577578
7 + 33577571 = 33577578
31 + 33577547 = 33577578
61 + 33577517 = 33577578
149 + 33577429 = 33577578
197 + 33577381 = 33577578
239 + 33577339 = 33577578
257 + 33577321 = 33577578

Showing the first eight; more decompositions exist.
