Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491370, here are decompositions:

7 + 33491363 = 33491370
37 + 33491333 = 33491370
67 + 33491303 = 33491370
103 + 33491267 = 33491370
109 + 33491261 = 33491370
137 + 33491233 = 33491370
149 + 33491221 = 33491370
167 + 33491203 = 33491370

Showing the first eight; more decompositions exist.
