Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33547580, here are decompositions:

37 + 33547543 = 33547580
43 + 33547537 = 33547580
67 + 33547513 = 33547580
163 + 33547417 = 33547580
193 + 33547387 = 33547580
271 + 33547309 = 33547580
337 + 33547243 = 33547580
433 + 33547147 = 33547580

Showing the first eight; more decompositions exist.
