Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188546, here are decompositions:

13 + 188533 = 188546
19 + 188527 = 188546
73 + 188473 = 188546
103 + 188443 = 188546
109 + 188437 = 188546
139 + 188407 = 188546
157 + 188389 = 188546
223 + 188323 = 188546

Showing the first eight; more decompositions exist.
