Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33547840, here are decompositions:

71 + 33547769 = 33547840
101 + 33547739 = 33547840
113 + 33547727 = 33547840
233 + 33547607 = 33547840
251 + 33547589 = 33547840
257 + 33547583 = 33547840
311 + 33547529 = 33547840
383 + 33547457 = 33547840

Showing the first eight; more decompositions exist.
