Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12562, here are decompositions:
- 23 + 12539 = 12562
- 59 + 12503 = 12562
- 71 + 12491 = 12562
- 83 + 12479 = 12562
- 89 + 12473 = 12562
- 149 + 12413 = 12562
- 233 + 12329 = 12562
- 239 + 12323 = 12562
Showing the first eight; more decompositions exist.
