Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42886, here are decompositions:
- 23 + 42863 = 42886
- 47 + 42839 = 42886
- 89 + 42797 = 42886
- 113 + 42773 = 42886
- 149 + 42737 = 42886
- 167 + 42719 = 42886
- 197 + 42689 = 42886
- 317 + 42569 = 42886
Showing the first eight; more decompositions exist.
