Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156904, here are decompositions:
- 3 + 156901 = 156904
- 5 + 156899 = 156904
- 17 + 156887 = 156904
- 71 + 156833 = 156904
- 107 + 156797 = 156904
- 197 + 156707 = 156904
- 227 + 156677 = 156904
- 233 + 156671 = 156904
Showing the first eight; more decompositions exist.
