Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33479140, here are decompositions:

137 + 33479003 = 33479140
197 + 33478943 = 33479140
251 + 33478889 = 33479140
263 + 33478877 = 33479140
389 + 33478751 = 33479140
419 + 33478721 = 33479140
491 + 33478649 = 33479140
557 + 33478583 = 33479140

Showing the first eight; more decompositions exist.
