Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 886, here are decompositions:
- 3 + 883 = 886
- 5 + 881 = 886
- 23 + 863 = 886
- 29 + 857 = 886
- 47 + 839 = 886
- 59 + 827 = 886
- 89 + 797 = 886
- 113 + 773 = 886
Showing the first eight; more decompositions exist.
