Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71870, here are decompositions:
- 3 + 71867 = 71870
- 61 + 71809 = 71870
- 109 + 71761 = 71870
- 151 + 71719 = 71870
- 157 + 71713 = 71870
- 163 + 71707 = 71870
- 199 + 71671 = 71870
- 223 + 71647 = 71870
Showing the first eight; more decompositions exist.
