Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104420, here are decompositions:

3 + 104417 = 104420
37 + 104383 = 104420
73 + 104347 = 104420
97 + 104323 = 104420
109 + 104311 = 104420
139 + 104281 = 104420
181 + 104239 = 104420
241 + 104179 = 104420

Showing the first eight; more decompositions exist.
