Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157270, here are decompositions:
- 11 + 157259 = 157270
- 17 + 157253 = 157270
- 23 + 157247 = 157270
- 41 + 157229 = 157270
- 53 + 157217 = 157270
- 59 + 157211 = 157270
- 89 + 157181 = 157270
- 107 + 157163 = 157270
Showing the first eight; more decompositions exist.
