Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33477890, here are decompositions:

7 + 33477883 = 33477890
73 + 33477817 = 33477890
97 + 33477793 = 33477890
211 + 33477679 = 33477890
241 + 33477649 = 33477890
331 + 33477559 = 33477890
337 + 33477553 = 33477890
367 + 33477523 = 33477890

Showing the first eight; more decompositions exist.
