Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561866, here are decompositions:

67 + 33561799 = 33561866
97 + 33561769 = 33561866
193 + 33561673 = 33561866
307 + 33561559 = 33561866
397 + 33561469 = 33561866
487 + 33561379 = 33561866
523 + 33561343 = 33561866
673 + 33561193 = 33561866

Showing the first eight; more decompositions exist.
