Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33485872, here are decompositions:

5 + 33485867 = 33485872
41 + 33485831 = 33485872
53 + 33485819 = 33485872
83 + 33485789 = 33485872
131 + 33485741 = 33485872
359 + 33485513 = 33485872
389 + 33485483 = 33485872
491 + 33485381 = 33485872

Showing the first eight; more decompositions exist.
