Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77906, here are decompositions:
- 7 + 77899 = 77906
- 13 + 77893 = 77906
- 43 + 77863 = 77906
- 67 + 77839 = 77906
- 109 + 77797 = 77906
- 163 + 77743 = 77906
- 193 + 77713 = 77906
- 337 + 77569 = 77906
Showing the first eight; more decompositions exist.
