Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538572, here are decompositions:

29 + 33538543 = 33538572
61 + 33538511 = 33538572
73 + 33538499 = 33538572
103 + 33538469 = 33538572
131 + 33538441 = 33538572
229 + 33538343 = 33538572
233 + 33538339 = 33538572
251 + 33538321 = 33538572

Showing the first eight; more decompositions exist.
