Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618394, here are decompositions:

71 + 33618323 = 33618394
233 + 33618161 = 33618394
431 + 33617963 = 33618394
461 + 33617933 = 33618394
587 + 33617807 = 33618394
617 + 33617777 = 33618394
647 + 33617747 = 33618394
683 + 33617711 = 33618394

Showing the first eight; more decompositions exist.
