Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30402, here are decompositions:

11 + 30391 = 30402
13 + 30389 = 30402
61 + 30341 = 30402
79 + 30323 = 30402
83 + 30319 = 30402
89 + 30313 = 30402
109 + 30293 = 30402
131 + 30271 = 30402

Showing the first eight; more decompositions exist.
