Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507778, here are decompositions:

41 + 33507737 = 33507778
89 + 33507689 = 33507778
107 + 33507671 = 33507778
131 + 33507647 = 33507778
137 + 33507641 = 33507778
167 + 33507611 = 33507778
179 + 33507599 = 33507778
401 + 33507377 = 33507778

Showing the first eight; more decompositions exist.
