Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31098, here are decompositions:
- 7 + 31091 = 31098
- 17 + 31081 = 31098
- 19 + 31079 = 31098
- 29 + 31069 = 31098
- 47 + 31051 = 31098
- 59 + 31039 = 31098
- 79 + 31019 = 31098
- 127 + 30971 = 31098
Showing the first eight; more decompositions exist.
