Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33547842, here are decompositions:

11 + 33547831 = 33547842
73 + 33547769 = 33547842
79 + 33547763 = 33547842
103 + 33547739 = 33547842
113 + 33547729 = 33547842
313 + 33547529 = 33547842
353 + 33547489 = 33547842
409 + 33547433 = 33547842

Showing the first eight; more decompositions exist.
