Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481402, here are decompositions:

23 + 481379 = 481402
29 + 481373 = 481402
59 + 481343 = 481402
101 + 481301 = 481402
191 + 481211 = 481402
269 + 481133 = 481402
293 + 481109 = 481402
359 + 481043 = 481402

Showing the first eight; more decompositions exist.
