Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531780, here are decompositions:

31 + 33531749 = 33531780
43 + 33531737 = 33531780
101 + 33531679 = 33531780
109 + 33531671 = 33531780
127 + 33531653 = 33531780
167 + 33531613 = 33531780
193 + 33531587 = 33531780
239 + 33531541 = 33531780

Showing the first eight; more decompositions exist.
