Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30406, here are decompositions:

3 + 30403 = 30406
17 + 30389 = 30406
59 + 30347 = 30406
83 + 30323 = 30406
113 + 30293 = 30406
137 + 30269 = 30406
269 + 30137 = 30406
293 + 30113 = 30406

Showing the first eight; more decompositions exist.
