Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33494728, here are decompositions:

101 + 33494627 = 33494728
149 + 33494579 = 33494728
167 + 33494561 = 33494728
317 + 33494411 = 33494728
419 + 33494309 = 33494728
431 + 33494297 = 33494728
677 + 33494051 = 33494728
821 + 33493907 = 33494728

Showing the first eight; more decompositions exist.
