Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71620, here are decompositions:
- 23 + 71597 = 71620
- 71 + 71549 = 71620
- 83 + 71537 = 71620
- 137 + 71483 = 71620
- 149 + 71471 = 71620
- 167 + 71453 = 71620
- 191 + 71429 = 71620
- 233 + 71387 = 71620
Showing the first eight; more decompositions exist.
