Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557974, here are decompositions:

53 + 33557921 = 33557974
83 + 33557891 = 33557974
137 + 33557837 = 33557974
167 + 33557807 = 33557974
293 + 33557681 = 33557974
311 + 33557663 = 33557974
347 + 33557627 = 33557974
431 + 33557543 = 33557974

Showing the first eight; more decompositions exist.
