Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531530, here are decompositions:

3 + 33531527 = 33531530
31 + 33531499 = 33531530
61 + 33531469 = 33531530
79 + 33531451 = 33531530
103 + 33531427 = 33531530
127 + 33531403 = 33531530
139 + 33531391 = 33531530
181 + 33531349 = 33531530

Showing the first eight; more decompositions exist.
