Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104912, here are decompositions:

43 + 104869 = 104912
61 + 104851 = 104912
109 + 104803 = 104912
139 + 104773 = 104912
151 + 104761 = 104912
211 + 104701 = 104912
229 + 104683 = 104912
421 + 104491 = 104912

Showing the first eight; more decompositions exist.
