Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33494778, here are decompositions:

7 + 33494771 = 33494778
17 + 33494761 = 33494778
19 + 33494759 = 33494778
29 + 33494749 = 33494778
101 + 33494677 = 33494778
151 + 33494627 = 33494778
167 + 33494611 = 33494778
199 + 33494579 = 33494778

Showing the first eight; more decompositions exist.
