Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33479872, here are decompositions:

3 + 33479869 = 33479872
11 + 33479861 = 33479872
53 + 33479819 = 33479872
59 + 33479813 = 33479872
113 + 33479759 = 33479872
131 + 33479741 = 33479872
233 + 33479639 = 33479872
269 + 33479603 = 33479872

Showing the first eight; more decompositions exist.
