Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20360, here are decompositions:
- 3 + 20357 = 20360
- 7 + 20353 = 20360
- 13 + 20347 = 20360
- 19 + 20341 = 20360
- 37 + 20323 = 20360
- 73 + 20287 = 20360
- 127 + 20233 = 20360
- 199 + 20161 = 20360
Showing the first eight; more decompositions exist.
