Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185650, here are decompositions:

29 + 185621 = 185650
83 + 185567 = 185650
107 + 185543 = 185650
131 + 185519 = 185650
167 + 185483 = 185650
173 + 185477 = 185650
281 + 185369 = 185650
347 + 185303 = 185650

Showing the first eight; more decompositions exist.
