Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164586, here are decompositions:

5 + 164581 = 164586
17 + 164569 = 164586
73 + 164513 = 164586
83 + 164503 = 164586
109 + 164477 = 164586
137 + 164449 = 164586
139 + 164447 = 164586
157 + 164429 = 164586

Showing the first eight; more decompositions exist.
