Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8430, here are decompositions:

7 + 8423 = 8430
11 + 8419 = 8430
41 + 8389 = 8430
43 + 8387 = 8430
53 + 8377 = 8430
61 + 8369 = 8430
67 + 8363 = 8430
101 + 8329 = 8430

Showing the first eight; more decompositions exist.
