Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531642, here are decompositions:

29 + 33531613 = 33531642
31 + 33531611 = 33531642
83 + 33531559 = 33531642
101 + 33531541 = 33531642
139 + 33531503 = 33531642
163 + 33531479 = 33531642
173 + 33531469 = 33531642
191 + 33531451 = 33531642

Showing the first eight; more decompositions exist.
