Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157342, here are decompositions:
- 71 + 157271 = 157342
- 83 + 157259 = 157342
- 89 + 157253 = 157342
- 113 + 157229 = 157342
- 131 + 157211 = 157342
- 179 + 157163 = 157342
- 233 + 157109 = 157342
- 239 + 157103 = 157342
Showing the first eight; more decompositions exist.
