Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5430, here are decompositions:

11 + 5419 = 5430
13 + 5417 = 5430
17 + 5413 = 5430
23 + 5407 = 5430
31 + 5399 = 5430
37 + 5393 = 5430
43 + 5387 = 5430
79 + 5351 = 5430

Showing the first eight; more decompositions exist.
