Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156256, here are decompositions:
- 3 + 156253 = 156256
- 29 + 156227 = 156256
- 137 + 156119 = 156256
- 167 + 156089 = 156256
- 197 + 156059 = 156256
- 479 + 155777 = 156256
- 509 + 155747 = 156256
- 557 + 155699 = 156256
Showing the first eight; more decompositions exist.
