Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538142, here are decompositions:

13 + 33538129 = 33538142
61 + 33538081 = 33538142
73 + 33538069 = 33538142
139 + 33538003 = 33538142
181 + 33537961 = 33538142
223 + 33537919 = 33538142
373 + 33537769 = 33538142
433 + 33537709 = 33538142

Showing the first eight; more decompositions exist.
