Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21350, here are decompositions:

3 + 21347 = 21350
31 + 21319 = 21350
37 + 21313 = 21350
67 + 21283 = 21350
73 + 21277 = 21350
103 + 21247 = 21350
139 + 21211 = 21350
157 + 21193 = 21350

Showing the first eight; more decompositions exist.
