Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126546, here are decompositions:
- 5 + 126541 = 126546
- 29 + 126517 = 126546
- 47 + 126499 = 126546
- 53 + 126493 = 126546
- 59 + 126487 = 126546
- 73 + 126473 = 126546
- 89 + 126457 = 126546
- 103 + 126443 = 126546
Showing the first eight; more decompositions exist.
