Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531420, here are decompositions:

7 + 33531413 = 33531420
17 + 33531403 = 33531420
23 + 33531397 = 33531420
29 + 33531391 = 33531420
31 + 33531389 = 33531420
67 + 33531353 = 33531420
71 + 33531349 = 33531420
73 + 33531347 = 33531420

Showing the first eight; more decompositions exist.
