Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185706, here are decompositions:

7 + 185699 = 185706
13 + 185693 = 185706
23 + 185683 = 185706
29 + 185677 = 185706
107 + 185599 = 185706
113 + 185593 = 185706
137 + 185569 = 185706
139 + 185567 = 185706

Showing the first eight; more decompositions exist.
