Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71406, here are decompositions:
- 7 + 71399 = 71406
- 17 + 71389 = 71406
- 19 + 71387 = 71406
- 43 + 71363 = 71406
- 47 + 71359 = 71406
- 53 + 71353 = 71406
- 59 + 71347 = 71406
- 67 + 71339 = 71406
Showing the first eight; more decompositions exist.
