Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478440, here are decompositions:

7 + 33478433 = 33478440
19 + 33478421 = 33478440
29 + 33478411 = 33478440
53 + 33478387 = 33478440
103 + 33478337 = 33478440
109 + 33478331 = 33478440
157 + 33478283 = 33478440
167 + 33478273 = 33478440

Showing the first eight; more decompositions exist.
