Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109490, here are decompositions:

19 + 109471 = 109490
37 + 109453 = 109490
67 + 109423 = 109490
103 + 109387 = 109490
127 + 109363 = 109490
193 + 109297 = 109490
211 + 109279 = 109490
223 + 109267 = 109490

Showing the first eight; more decompositions exist.
