Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188424, here are decompositions:

7 + 188417 = 188424
17 + 188407 = 188424
23 + 188401 = 188424
73 + 188351 = 188424
101 + 188323 = 188424
107 + 188317 = 188424
113 + 188311 = 188424
151 + 188273 = 188424

Showing the first eight; more decompositions exist.
