Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33472978, here are decompositions:

17 + 33472961 = 33472978
41 + 33472937 = 33472978
191 + 33472787 = 33472978
281 + 33472697 = 33472978
389 + 33472589 = 33472978
401 + 33472577 = 33472978
479 + 33472499 = 33472978
491 + 33472487 = 33472978

Showing the first eight; more decompositions exist.
