Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21482, here are decompositions:

103 + 21379 = 21482
163 + 21319 = 21482
199 + 21283 = 21482
271 + 21211 = 21482
313 + 21169 = 21482
421 + 21061 = 21482
463 + 21019 = 21482
499 + 20983 = 21482

Showing the first eight; more decompositions exist.
