Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71906, here are decompositions:
- 7 + 71899 = 71906
- 19 + 71887 = 71906
- 97 + 71809 = 71906
- 193 + 71713 = 71906
- 199 + 71707 = 71906
- 313 + 71593 = 71906
- 337 + 71569 = 71906
- 379 + 71527 = 71906
Showing the first eight; more decompositions exist.
