Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21462, here are decompositions:
- 29 + 21433 = 21462
- 43 + 21419 = 21462
- 61 + 21401 = 21462
- 71 + 21391 = 21462
- 79 + 21383 = 21462
- 83 + 21379 = 21462
- 139 + 21323 = 21462
- 149 + 21313 = 21462
Showing the first eight; more decompositions exist.
