Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531784, here are decompositions:

3 + 33531781 = 33531784
47 + 33531737 = 33531784
113 + 33531671 = 33531784
131 + 33531653 = 33531784
173 + 33531611 = 33531784
197 + 33531587 = 33531784
257 + 33531527 = 33531784
281 + 33531503 = 33531784

Showing the first eight; more decompositions exist.
