Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493740, here are decompositions:

23 + 33493717 = 33493740
47 + 33493693 = 33493740
67 + 33493673 = 33493740
101 + 33493639 = 33493740
113 + 33493627 = 33493740
127 + 33493613 = 33493740
139 + 33493601 = 33493740
149 + 33493591 = 33493740

Showing the first eight; more decompositions exist.
