Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81350, here are decompositions:

7 + 81343 = 81350
19 + 81331 = 81350
43 + 81307 = 81350
67 + 81283 = 81350
127 + 81223 = 81350
151 + 81199 = 81350
193 + 81157 = 81350
307 + 81043 = 81350

Showing the first eight; more decompositions exist.
