Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478442, here are decompositions:

3 + 33478439 = 33478442
31 + 33478411 = 33478442
211 + 33478231 = 33478442
241 + 33478201 = 33478442
331 + 33478111 = 33478442
379 + 33478063 = 33478442
433 + 33478009 = 33478442
883 + 33477559 = 33478442

Showing the first eight; more decompositions exist.
