Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33607840, here are decompositions:

23 + 33607817 = 33607840
107 + 33607733 = 33607840
113 + 33607727 = 33607840
137 + 33607703 = 33607840
293 + 33607547 = 33607840
311 + 33607529 = 33607840
419 + 33607421 = 33607840
449 + 33607391 = 33607840

Showing the first eight; more decompositions exist.
