Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491430, here are decompositions:

13 + 33491417 = 33491430
43 + 33491387 = 33491430
59 + 33491371 = 33491430
61 + 33491369 = 33491430
67 + 33491363 = 33491430
97 + 33491333 = 33491430
127 + 33491303 = 33491430
163 + 33491267 = 33491430

Showing the first eight; more decompositions exist.
