Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531442, here are decompositions:

3 + 33531439 = 33531442
11 + 33531431 = 33531442
29 + 33531413 = 33531442
53 + 33531389 = 33531442
89 + 33531353 = 33531442
173 + 33531269 = 33531442
359 + 33531083 = 33531442
383 + 33531059 = 33531442

Showing the first eight; more decompositions exist.
