Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124536, here are decompositions:
- 7 + 124529 = 124536
- 23 + 124513 = 124536
- 43 + 124493 = 124536
- 47 + 124489 = 124536
- 59 + 124477 = 124536
- 89 + 124447 = 124536
- 103 + 124433 = 124536
- 107 + 124429 = 124536
Showing the first eight; more decompositions exist.
