Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30478, here are decompositions:

11 + 30467 = 30478
29 + 30449 = 30478
47 + 30431 = 30478
89 + 30389 = 30478
131 + 30347 = 30478
137 + 30341 = 30478
281 + 30197 = 30478
317 + 30161 = 30478

Showing the first eight; more decompositions exist.
