Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33623490, here are decompositions:

31 + 33623459 = 33623490
71 + 33623419 = 33623490
97 + 33623393 = 33623490
101 + 33623389 = 33623490
127 + 33623363 = 33623490
137 + 33623353 = 33623490
139 + 33623351 = 33623490
149 + 33623341 = 33623490

Showing the first eight; more decompositions exist.
