Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120930, here are decompositions:
- 11 + 120919 = 120930
- 13 + 120917 = 120930
- 23 + 120907 = 120930
- 31 + 120899 = 120930
- 41 + 120889 = 120930
- 53 + 120877 = 120930
- 59 + 120871 = 120930
- 67 + 120863 = 120930
Showing the first eight; more decompositions exist.
