Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33477978, here are decompositions:

7 + 33477971 = 33477978
47 + 33477931 = 33477978
97 + 33477881 = 33477978
379 + 33477599 = 33477978
419 + 33477559 = 33477978
461 + 33477517 = 33477978
487 + 33477491 = 33477978
587 + 33477391 = 33477978

Showing the first eight; more decompositions exist.
