Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491280, here are decompositions:

13 + 33491267 = 33491280
19 + 33491261 = 33491280
47 + 33491233 = 33491280
59 + 33491221 = 33491280
127 + 33491153 = 33491280
131 + 33491149 = 33491280
139 + 33491141 = 33491280
181 + 33491099 = 33491280

Showing the first eight; more decompositions exist.
