Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33479142, here are decompositions:

23 + 33479119 = 33479142
79 + 33479063 = 33479142
131 + 33479011 = 33479142
139 + 33479003 = 33479142
163 + 33478979 = 33479142
199 + 33478943 = 33479142
239 + 33478903 = 33479142
383 + 33478759 = 33479142

Showing the first eight; more decompositions exist.
