Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33479490, here are decompositions:

7 + 33479483 = 33479490
41 + 33479449 = 33479490
43 + 33479447 = 33479490
73 + 33479417 = 33479490
113 + 33479377 = 33479490
137 + 33479353 = 33479490
139 + 33479351 = 33479490
167 + 33479323 = 33479490

Showing the first eight; more decompositions exist.
