Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33502490, here are decompositions:

13 + 33502477 = 33502490
61 + 33502429 = 33502490
127 + 33502363 = 33502490
163 + 33502327 = 33502490
193 + 33502297 = 33502490
223 + 33502267 = 33502490
337 + 33502153 = 33502490
349 + 33502141 = 33502490

Showing the first eight; more decompositions exist.
