Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33625820, here are decompositions:

3 + 33625817 = 33625820
97 + 33625723 = 33625820
139 + 33625681 = 33625820
229 + 33625591 = 33625820
307 + 33625513 = 33625820
373 + 33625447 = 33625820
409 + 33625411 = 33625820
457 + 33625363 = 33625820

Showing the first eight; more decompositions exist.
