Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538542, here are decompositions:

19 + 33538523 = 33538542
31 + 33538511 = 33538542
43 + 33538499 = 33538542
61 + 33538481 = 33538542
73 + 33538469 = 33538542
101 + 33538441 = 33538542
139 + 33538403 = 33538542
199 + 33538343 = 33538542

Showing the first eight; more decompositions exist.
