Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551972, here are decompositions:

19 + 33551953 = 33551972
79 + 33551893 = 33551972
199 + 33551773 = 33551972
241 + 33551731 = 33551972
379 + 33551593 = 33551972
439 + 33551533 = 33551972
463 + 33551509 = 33551972
523 + 33551449 = 33551972

Showing the first eight; more decompositions exist.
