Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12586, here are decompositions:
- 3 + 12583 = 12586
- 17 + 12569 = 12586
- 47 + 12539 = 12586
- 59 + 12527 = 12586
- 83 + 12503 = 12586
- 89 + 12497 = 12586
- 107 + 12479 = 12586
- 113 + 12473 = 12586
Showing the first eight; more decompositions exist.
