Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12526, here are decompositions:
- 23 + 12503 = 12526
- 29 + 12497 = 12526
- 47 + 12479 = 12526
- 53 + 12473 = 12526
- 89 + 12437 = 12526
- 113 + 12413 = 12526
- 149 + 12377 = 12526
- 179 + 12347 = 12526
Showing the first eight; more decompositions exist.
