Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507786, here are decompositions:

5 + 33507781 = 33507786
7 + 33507779 = 33507786
23 + 33507763 = 33507786
43 + 33507743 = 33507786
97 + 33507689 = 33507786
107 + 33507679 = 33507786
139 + 33507647 = 33507786
163 + 33507623 = 33507786

Showing the first eight; more decompositions exist.
