Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157522, here are decompositions:
- 3 + 157519 = 157522
- 89 + 157433 = 157522
- 173 + 157349 = 157522
- 251 + 157271 = 157522
- 263 + 157259 = 157522
- 269 + 157253 = 157522
- 293 + 157229 = 157522
- 311 + 157211 = 157522
Showing the first eight; more decompositions exist.
