Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493388, here are decompositions:

67 + 33493321 = 33493388
79 + 33493309 = 33493388
109 + 33493279 = 33493388
307 + 33493081 = 33493388
499 + 33492889 = 33493388
541 + 33492847 = 33493388
661 + 33492727 = 33493388
751 + 33492637 = 33493388

Showing the first eight; more decompositions exist.
