Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31068, here are decompositions:
- 5 + 31063 = 31068
- 17 + 31051 = 31068
- 29 + 31039 = 31068
- 97 + 30971 = 31068
- 127 + 30941 = 31068
- 131 + 30937 = 31068
- 137 + 30931 = 31068
- 157 + 30911 = 31068
Showing the first eight; more decompositions exist.
