Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507440, here are decompositions:

61 + 33507379 = 33507440
181 + 33507259 = 33507440
193 + 33507247 = 33507440
229 + 33507211 = 33507440
331 + 33507109 = 33507440
619 + 33506821 = 33507440
643 + 33506797 = 33507440
751 + 33506689 = 33507440

Showing the first eight; more decompositions exist.
