Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 106978, here are decompositions:
- 17 + 106961 = 106978
- 29 + 106949 = 106978
- 41 + 106937 = 106978
- 71 + 106907 = 106978
- 101 + 106877 = 106978
- 107 + 106871 = 106978
- 191 + 106787 = 106978
- 197 + 106781 = 106978
Showing the first eight; more decompositions exist.
