Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71230, here are decompositions:
- 59 + 71171 = 71230
- 83 + 71147 = 71230
- 101 + 71129 = 71230
- 149 + 71081 = 71230
- 191 + 71039 = 71230
- 233 + 70997 = 71230
- 239 + 70991 = 71230
- 251 + 70979 = 71230
Showing the first eight; more decompositions exist.
