Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531188, here are decompositions:

127 + 33531061 = 33531188
139 + 33531049 = 33531188
157 + 33531031 = 33531188
211 + 33530977 = 33531188
331 + 33530857 = 33531188
487 + 33530701 = 33531188
571 + 33530617 = 33531188
619 + 33530569 = 33531188

Showing the first eight; more decompositions exist.
