Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493890, here are decompositions:

13 + 33493877 = 33493890
19 + 33493871 = 33493890
61 + 33493829 = 33493890
83 + 33493807 = 33493890
107 + 33493783 = 33493890
113 + 33493777 = 33493890
173 + 33493717 = 33493890
197 + 33493693 = 33493890

Showing the first eight; more decompositions exist.
