Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555940, here are decompositions:

239 + 33555701 = 33555940
281 + 33555659 = 33555940
293 + 33555647 = 33555940
311 + 33555629 = 33555940
443 + 33555497 = 33555940
479 + 33555461 = 33555940
491 + 33555449 = 33555940
521 + 33555419 = 33555940

Showing the first eight; more decompositions exist.
