Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2906, here are decompositions:
- 3 + 2903 = 2906
- 19 + 2887 = 2906
- 73 + 2833 = 2906
- 103 + 2803 = 2906
- 109 + 2797 = 2906
- 139 + 2767 = 2906
- 157 + 2749 = 2906
- 193 + 2713 = 2906
Showing the first eight; more decompositions exist.
