Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521386, here are decompositions:

149 + 33521237 = 33521386
167 + 33521219 = 33521386
347 + 33521039 = 33521386
383 + 33521003 = 33521386
419 + 33520967 = 33521386
467 + 33520919 = 33521386
557 + 33520829 = 33521386
677 + 33520709 = 33521386

Showing the first eight; more decompositions exist.
