Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157372, here are decompositions:
- 23 + 157349 = 157372
- 101 + 157271 = 157372
- 113 + 157259 = 157372
- 191 + 157181 = 157372
- 239 + 157133 = 157372
- 263 + 157109 = 157372
- 269 + 157103 = 157372
- 311 + 157061 = 157372
Showing the first eight; more decompositions exist.
