Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120986, here are decompositions:
- 43 + 120943 = 120986
- 67 + 120919 = 120986
- 79 + 120907 = 120986
- 97 + 120889 = 120986
- 109 + 120877 = 120986
- 139 + 120847 = 120986
- 157 + 120829 = 120986
- 163 + 120823 = 120986
Showing the first eight; more decompositions exist.
