Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33480380, here are decompositions:

97 + 33480283 = 33480380
139 + 33480241 = 33480380
277 + 33480103 = 33480380
337 + 33480043 = 33480380
379 + 33480001 = 33480380
397 + 33479983 = 33480380
607 + 33479773 = 33480380
643 + 33479737 = 33480380

Showing the first eight; more decompositions exist.
