Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103490, here are decompositions:

7 + 103483 = 103490
19 + 103471 = 103490
67 + 103423 = 103490
97 + 103393 = 103490
103 + 103387 = 103490
157 + 103333 = 103490
199 + 103291 = 103490
307 + 103183 = 103490

Showing the first eight; more decompositions exist.
