Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33533642, here are decompositions:

151 + 33533491 = 33533642
199 + 33533443 = 33533642
211 + 33533431 = 33533642
313 + 33533329 = 33533642
349 + 33533293 = 33533642
421 + 33533221 = 33533642
613 + 33533029 = 33533642
673 + 33532969 = 33533642

Showing the first eight; more decompositions exist.
