Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531856, here are decompositions:

3 + 33531853 = 33531856
107 + 33531749 = 33531856
269 + 33531587 = 33531856
353 + 33531503 = 33531856
383 + 33531473 = 33531856
389 + 33531467 = 33531856
443 + 33531413 = 33531856
467 + 33531389 = 33531856

Showing the first eight; more decompositions exist.
