Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71500, here are decompositions:
- 17 + 71483 = 71500
- 29 + 71471 = 71500
- 47 + 71453 = 71500
- 71 + 71429 = 71500
- 89 + 71411 = 71500
- 101 + 71399 = 71500
- 113 + 71387 = 71500
- 137 + 71363 = 71500
Showing the first eight; more decompositions exist.
