Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531278, here are decompositions:

31 + 33531247 = 33531278
181 + 33531097 = 33531278
229 + 33531049 = 33531278
307 + 33530971 = 33531278
379 + 33530899 = 33531278
421 + 33530857 = 33531278
577 + 33530701 = 33531278
601 + 33530677 = 33531278

Showing the first eight; more decompositions exist.
