Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5906, here are decompositions:
- 3 + 5903 = 5906
- 37 + 5869 = 5906
- 67 + 5839 = 5906
- 79 + 5827 = 5906
- 127 + 5779 = 5906
- 157 + 5749 = 5906
- 163 + 5743 = 5906
- 223 + 5683 = 5906
Showing the first eight; more decompositions exist.
