Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491378, here are decompositions:

7 + 33491371 = 33491378
157 + 33491221 = 33491378
229 + 33491149 = 33491378
337 + 33491041 = 33491378
379 + 33490999 = 33491378
397 + 33490981 = 33491378
577 + 33490801 = 33491378
601 + 33490777 = 33491378

Showing the first eight; more decompositions exist.
