Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12550, here are decompositions:
- 3 + 12547 = 12550
- 11 + 12539 = 12550
- 23 + 12527 = 12550
- 47 + 12503 = 12550
- 53 + 12497 = 12550
- 59 + 12491 = 12550
- 71 + 12479 = 12550
- 113 + 12437 = 12550
Showing the first eight; more decompositions exist.
