Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104490, here are decompositions:

11 + 104479 = 104490
17 + 104473 = 104490
19 + 104471 = 104490
31 + 104459 = 104490
73 + 104417 = 104490
97 + 104393 = 104490
107 + 104383 = 104490
109 + 104381 = 104490

Showing the first eight; more decompositions exist.
