Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33623890, here are decompositions:

11 + 33623879 = 33623890
23 + 33623867 = 33623890
71 + 33623819 = 33623890
191 + 33623699 = 33623890
239 + 33623651 = 33623890
257 + 33623633 = 33623890
269 + 33623621 = 33623890
281 + 33623609 = 33623890

Showing the first eight; more decompositions exist.
