Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104408, here are decompositions:

61 + 104347 = 104408
97 + 104311 = 104408
127 + 104281 = 104408
229 + 104179 = 104408
349 + 104059 = 104408
439 + 103969 = 104408
457 + 103951 = 104408
541 + 103867 = 104408

Showing the first eight; more decompositions exist.
