Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71028, here are decompositions:
- 5 + 71023 = 71028
- 17 + 71011 = 71028
- 29 + 70999 = 71028
- 31 + 70997 = 71028
- 37 + 70991 = 71028
- 47 + 70981 = 71028
- 59 + 70969 = 71028
- 71 + 70957 = 71028
Showing the first eight; more decompositions exist.
