Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156874, here are decompositions:
- 41 + 156833 = 156874
- 167 + 156707 = 156874
- 191 + 156683 = 156874
- 197 + 156677 = 156874
- 233 + 156641 = 156874
- 251 + 156623 = 156874
- 281 + 156593 = 156874
- 353 + 156521 = 156874
Showing the first eight; more decompositions exist.
