Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10478, here are decompositions:

19 + 10459 = 10478
79 + 10399 = 10478
109 + 10369 = 10478
157 + 10321 = 10478
211 + 10267 = 10478
337 + 10141 = 10478
367 + 10111 = 10478
379 + 10099 = 10478

Showing the first eight; more decompositions exist.
