Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33477638, here are decompositions:

79 + 33477559 = 33477638
157 + 33477481 = 33477638
307 + 33477331 = 33477638
331 + 33477307 = 33477638
367 + 33477271 = 33477638
661 + 33476977 = 33477638
709 + 33476929 = 33477638
751 + 33476887 = 33477638

Showing the first eight; more decompositions exist.
