Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33488780, here are decompositions:

97 + 33488683 = 33488780
181 + 33488599 = 33488780
211 + 33488569 = 33488780
223 + 33488557 = 33488780
271 + 33488509 = 33488780
313 + 33488467 = 33488780
331 + 33488449 = 33488780
373 + 33488407 = 33488780

Showing the first eight; more decompositions exist.
