Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531440, here are decompositions:

13 + 33531427 = 33531440
37 + 33531403 = 33531440
43 + 33531397 = 33531440
157 + 33531283 = 33531440
193 + 33531247 = 33531440
211 + 33531229 = 33531440
379 + 33531061 = 33531440
409 + 33531031 = 33531440

Showing the first eight; more decompositions exist.
