Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83430, here are decompositions:

7 + 83423 = 83430
13 + 83417 = 83430
23 + 83407 = 83430
29 + 83401 = 83430
31 + 83399 = 83430
41 + 83389 = 83430
47 + 83383 = 83430
73 + 83357 = 83430

Showing the first eight; more decompositions exist.
