Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531878, here are decompositions:

31 + 33531847 = 33531878
97 + 33531781 = 33531878
199 + 33531679 = 33531878
337 + 33531541 = 33531878
379 + 33531499 = 33531878
409 + 33531469 = 33531878
439 + 33531439 = 33531878
487 + 33531391 = 33531878

Showing the first eight; more decompositions exist.
