Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531778, here are decompositions:

29 + 33531749 = 33531778
41 + 33531737 = 33531778
107 + 33531671 = 33531778
167 + 33531611 = 33531778
191 + 33531587 = 33531778
251 + 33531527 = 33531778
311 + 33531467 = 33531778
347 + 33531431 = 33531778

Showing the first eight; more decompositions exist.
