Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71560, here are decompositions:
- 11 + 71549 = 71560
- 23 + 71537 = 71560
- 89 + 71471 = 71560
- 107 + 71453 = 71560
- 131 + 71429 = 71560
- 149 + 71411 = 71560
- 173 + 71387 = 71560
- 197 + 71363 = 71560
Showing the first eight; more decompositions exist.
