Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103646, here are decompositions:

3 + 103643 = 103646
73 + 103573 = 103646
79 + 103567 = 103646
97 + 103549 = 103646
163 + 103483 = 103646
223 + 103423 = 103646
313 + 103333 = 103646
409 + 103237 = 103646

Showing the first eight; more decompositions exist.
