Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33503872, here are decompositions:

23 + 33503849 = 33503872
29 + 33503843 = 33503872
239 + 33503633 = 33503872
419 + 33503453 = 33503872
443 + 33503429 = 33503872
461 + 33503411 = 33503872
503 + 33503369 = 33503872
509 + 33503363 = 33503872

Showing the first eight; more decompositions exist.
