Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81430, here are decompositions:

29 + 81401 = 81430
59 + 81371 = 81430
71 + 81359 = 81430
131 + 81299 = 81430
137 + 81293 = 81430
149 + 81281 = 81430
191 + 81239 = 81430
197 + 81233 = 81430

Showing the first eight; more decompositions exist.
