Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103478, here are decompositions:

7 + 103471 = 103478
79 + 103399 = 103478
241 + 103237 = 103478
307 + 103171 = 103478
337 + 103141 = 103478
379 + 103099 = 103478
409 + 103069 = 103478
547 + 102931 = 103478

Showing the first eight; more decompositions exist.
