Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491842, here are decompositions:

5 + 33491837 = 33491842
11 + 33491831 = 33491842
101 + 33491741 = 33491842
113 + 33491729 = 33491842
149 + 33491693 = 33491842
239 + 33491603 = 33491842
281 + 33491561 = 33491842
353 + 33491489 = 33491842

Showing the first eight; more decompositions exist.
