Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491442, here are decompositions:

71 + 33491371 = 33491442
73 + 33491369 = 33491442
79 + 33491363 = 33491442
109 + 33491333 = 33491442
139 + 33491303 = 33491442
181 + 33491261 = 33491442
239 + 33491203 = 33491442
293 + 33491149 = 33491442

Showing the first eight; more decompositions exist.
