60 — Sexagesimal Base

60 is a composite number, even, a calendar year.

Sixty is the smallest number divisible by every integer from 1 to 6. The Babylonian sexagesimal (base-60) system is why we still have 60 seconds in a minute and 60 minutes in an hour.

Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 60, here are decompositions:

7 + 53 = 60
13 + 47 = 60
17 + 43 = 60
19 + 41 = 60
23 + 37 = 60
29 + 31 = 60
