Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581418, here are decompositions:

5 + 33581413 = 33581418
7 + 33581411 = 33581418
37 + 33581381 = 33581418
67 + 33581351 = 33581418
89 + 33581329 = 33581418
97 + 33581321 = 33581418
127 + 33581291 = 33581418
131 + 33581287 = 33581418

Showing the first eight; more decompositions exist.
