Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12402, here are decompositions:

11 + 12391 = 12402
23 + 12379 = 12402
29 + 12373 = 12402
59 + 12343 = 12402
73 + 12329 = 12402
79 + 12323 = 12402
101 + 12301 = 12402
113 + 12289 = 12402

Showing the first eight; more decompositions exist.
