Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531518, here are decompositions:

19 + 33531499 = 33531518
67 + 33531451 = 33531518
79 + 33531439 = 33531518
127 + 33531391 = 33531518
199 + 33531319 = 33531518
271 + 33531247 = 33531518
331 + 33531187 = 33531518
421 + 33531097 = 33531518

Showing the first eight; more decompositions exist.
