Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156940, here are decompositions:
- 41 + 156899 = 156940
- 53 + 156887 = 156940
- 107 + 156833 = 156940
- 191 + 156749 = 156940
- 233 + 156707 = 156940
- 257 + 156683 = 156940
- 263 + 156677 = 156940
- 269 + 156671 = 156940
Showing the first eight; more decompositions exist.
