Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545780, here are decompositions:

67 + 33545713 = 33545780
157 + 33545623 = 33545780
181 + 33545599 = 33545780
223 + 33545557 = 33545780
283 + 33545497 = 33545780
337 + 33545443 = 33545780
379 + 33545401 = 33545780
397 + 33545383 = 33545780

Showing the first eight; more decompositions exist.
