Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531868, here are decompositions:

131 + 33531737 = 33531868
197 + 33531671 = 33531868
257 + 33531611 = 33531868
281 + 33531587 = 33531868
389 + 33531479 = 33531868
401 + 33531467 = 33531868
479 + 33531389 = 33531868
521 + 33531347 = 33531868

Showing the first eight; more decompositions exist.
