Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104648, here are decompositions:

97 + 104551 = 104648
157 + 104491 = 104648
337 + 104311 = 104648
367 + 104281 = 104648
409 + 104239 = 104648
487 + 104161 = 104648
499 + 104149 = 104648
541 + 104107 = 104648

Showing the first eight; more decompositions exist.
