Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31102, here are decompositions:
- 11 + 31091 = 31102
- 23 + 31079 = 31102
- 83 + 31019 = 31102
- 89 + 31013 = 31102
- 131 + 30971 = 31102
- 191 + 30911 = 31102
- 233 + 30869 = 31102
- 251 + 30851 = 31102
Showing the first eight; more decompositions exist.
