Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30490, here are decompositions:

23 + 30467 = 30490
41 + 30449 = 30490
59 + 30431 = 30490
101 + 30389 = 30490
149 + 30341 = 30490
167 + 30323 = 30490
197 + 30293 = 30490
293 + 30197 = 30490

Showing the first eight; more decompositions exist.
