Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493686, here are decompositions:

13 + 33493673 = 33493686
47 + 33493639 = 33493686
59 + 33493627 = 33493686
67 + 33493619 = 33493686
73 + 33493613 = 33493686
113 + 33493573 = 33493686
137 + 33493549 = 33493686
157 + 33493529 = 33493686

Showing the first eight; more decompositions exist.
