Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71400, here are decompositions:
- 11 + 71389 = 71400
- 13 + 71387 = 71400
- 37 + 71363 = 71400
- 41 + 71359 = 71400
- 47 + 71353 = 71400
- 53 + 71347 = 71400
- 59 + 71341 = 71400
- 61 + 71339 = 71400
Showing the first eight; more decompositions exist.
