Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531842, here are decompositions:

61 + 33531781 = 33531842
163 + 33531679 = 33531842
181 + 33531661 = 33531842
229 + 33531613 = 33531842
283 + 33531559 = 33531842
373 + 33531469 = 33531842
439 + 33531403 = 33531842
523 + 33531319 = 33531842

Showing the first eight; more decompositions exist.
