Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71512, here are decompositions:
- 29 + 71483 = 71512
- 41 + 71471 = 71512
- 59 + 71453 = 71512
- 83 + 71429 = 71512
- 101 + 71411 = 71512
- 113 + 71399 = 71512
- 149 + 71363 = 71512
- 173 + 71339 = 71512
Showing the first eight; more decompositions exist.
