Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21062, here are decompositions:
- 3 + 21059 = 21062
- 31 + 21031 = 21062
- 43 + 21019 = 21062
- 61 + 21001 = 21062
- 79 + 20983 = 21062
- 103 + 20959 = 21062
- 163 + 20899 = 21062
- 313 + 20749 = 21062
Showing the first eight; more decompositions exist.
