Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185526, here are decompositions:

7 + 185519 = 185526
43 + 185483 = 185526
59 + 185467 = 185526
97 + 185429 = 185526
157 + 185369 = 185526
163 + 185363 = 185526
167 + 185359 = 185526
199 + 185327 = 185526

Showing the first eight; more decompositions exist.
