Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531418, here are decompositions:

5 + 33531413 = 33531418
29 + 33531389 = 33531418
71 + 33531347 = 33531418
149 + 33531269 = 33531418
251 + 33531167 = 33531418
359 + 33531059 = 33531418
419 + 33530999 = 33531418
449 + 33530969 = 33531418

Showing the first eight; more decompositions exist.
