Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481802, here are decompositions:

103 + 481699 = 481802
109 + 481693 = 481802
151 + 481651 = 481802
163 + 481639 = 481802
271 + 481531 = 481802
313 + 481489 = 481802
439 + 481363 = 481802
499 + 481303 = 481802

Showing the first eight; more decompositions exist.
