Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478260, here are decompositions:

7 + 478253 = 478260
17 + 478243 = 478260
19 + 478241 = 478260
47 + 478213 = 478260
53 + 478207 = 478260
61 + 478199 = 478260
71 + 478189 = 478260
89 + 478171 = 478260

Showing the first eight; more decompositions exist.
