Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561580, here are decompositions:

23 + 33561557 = 33561580
29 + 33561551 = 33561580
47 + 33561533 = 33561580
53 + 33561527 = 33561580
167 + 33561413 = 33561580
191 + 33561389 = 33561580
293 + 33561287 = 33561580
317 + 33561263 = 33561580

Showing the first eight; more decompositions exist.
