Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126486, here are decompositions:
- 5 + 126481 = 126486
- 13 + 126473 = 126486
- 29 + 126457 = 126486
- 43 + 126443 = 126486
- 53 + 126433 = 126486
- 89 + 126397 = 126486
- 127 + 126359 = 126486
- 137 + 126349 = 126486
Showing the first eight; more decompositions exist.
