Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531886, here are decompositions:

137 + 33531749 = 33531886
149 + 33531737 = 33531886
233 + 33531653 = 33531886
359 + 33531527 = 33531886
383 + 33531503 = 33531886
419 + 33531467 = 33531886
587 + 33531299 = 33531886
617 + 33531269 = 33531886

Showing the first eight; more decompositions exist.
