Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531686, here are decompositions:

7 + 33531679 = 33531686
73 + 33531613 = 33531686
109 + 33531577 = 33531686
127 + 33531559 = 33531686
283 + 33531403 = 33531686
337 + 33531349 = 33531686
367 + 33531319 = 33531686
439 + 33531247 = 33531686

Showing the first eight; more decompositions exist.
