Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531458, here are decompositions:

7 + 33531451 = 33531458
19 + 33531439 = 33531458
31 + 33531427 = 33531458
61 + 33531397 = 33531458
67 + 33531391 = 33531458
109 + 33531349 = 33531458
139 + 33531319 = 33531458
211 + 33531247 = 33531458

Showing the first eight; more decompositions exist.
