Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531380, here are decompositions:

31 + 33531349 = 33531380
61 + 33531319 = 33531380
97 + 33531283 = 33531380
151 + 33531229 = 33531380
193 + 33531187 = 33531380
283 + 33531097 = 33531380
331 + 33531049 = 33531380
349 + 33531031 = 33531380

Showing the first eight; more decompositions exist.
