Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23430, here are decompositions:

13 + 23417 = 23430
31 + 23399 = 23430
59 + 23371 = 23430
61 + 23369 = 23430
73 + 23357 = 23430
97 + 23333 = 23430
103 + 23327 = 23430
109 + 23321 = 23430

Showing the first eight; more decompositions exist.
