Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523430, here are decompositions:

3 + 523427 = 523430
13 + 523417 = 523430
43 + 523387 = 523430
73 + 523357 = 523430
79 + 523351 = 523430
97 + 523333 = 523430
211 + 523219 = 523430
223 + 523207 = 523430

Showing the first eight; more decompositions exist.
