Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146930, here are decompositions:
- 13 + 146917 = 146930
- 37 + 146893 = 146930
- 73 + 146857 = 146930
- 97 + 146833 = 146930
- 163 + 146767 = 146930
- 181 + 146749 = 146930
- 211 + 146719 = 146930
- 229 + 146701 = 146930
Showing the first eight; more decompositions exist.
