Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507220, here are decompositions:

53 + 33507167 = 33507220
83 + 33507137 = 33507220
113 + 33507107 = 33507220
191 + 33507029 = 33507220
317 + 33506903 = 33507220
401 + 33506819 = 33507220
419 + 33506801 = 33507220
443 + 33506777 = 33507220

Showing the first eight; more decompositions exist.
