Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545840, here are decompositions:

37 + 33545803 = 33545840
127 + 33545713 = 33545840
241 + 33545599 = 33545840
283 + 33545557 = 33545840
313 + 33545527 = 33545840
397 + 33545443 = 33545840
439 + 33545401 = 33545840
457 + 33545383 = 33545840

Showing the first eight; more decompositions exist.
