Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493142, here are decompositions:

3 + 33493139 = 33493142
61 + 33493081 = 33493142
79 + 33493063 = 33493142
139 + 33493003 = 33493142
271 + 33492871 = 33493142
349 + 33492793 = 33493142
601 + 33492541 = 33493142
769 + 33492373 = 33493142

Showing the first eight; more decompositions exist.
