Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71930, here are decompositions:
- 13 + 71917 = 71930
- 31 + 71899 = 71930
- 43 + 71887 = 71930
- 109 + 71821 = 71930
- 211 + 71719 = 71930
- 223 + 71707 = 71930
- 283 + 71647 = 71930
- 337 + 71593 = 71930
Showing the first eight; more decompositions exist.
