Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12544, here are decompositions:
- 3 + 12541 = 12544
- 5 + 12539 = 12544
- 17 + 12527 = 12544
- 41 + 12503 = 12544
- 47 + 12497 = 12544
- 53 + 12491 = 12544
- 71 + 12473 = 12544
- 107 + 12437 = 12544
Showing the first eight; more decompositions exist.
