Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491400, here are decompositions:

13 + 33491387 = 33491400
29 + 33491371 = 33491400
31 + 33491369 = 33491400
37 + 33491363 = 33491400
67 + 33491333 = 33491400
97 + 33491303 = 33491400
139 + 33491261 = 33491400
167 + 33491233 = 33491400

Showing the first eight; more decompositions exist.
