Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71586, here are decompositions:
- 17 + 71569 = 71586
- 23 + 71563 = 71586
- 37 + 71549 = 71586
- 59 + 71527 = 71586
- 83 + 71503 = 71586
- 103 + 71483 = 71586
- 107 + 71479 = 71586
- 113 + 71473 = 71586
Showing the first eight; more decompositions exist.
