Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 184380, here are decompositions:

11 + 184369 = 184380
29 + 184351 = 184380
43 + 184337 = 184380
47 + 184333 = 184380
59 + 184321 = 184380
71 + 184309 = 184380
89 + 184291 = 184380
101 + 184279 = 184380

Showing the first eight; more decompositions exist.
