Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157368, here are decompositions:
- 5 + 157363 = 157368
- 17 + 157351 = 157368
- 19 + 157349 = 157368
- 41 + 157327 = 157368
- 47 + 157321 = 157368
- 61 + 157307 = 157368
- 89 + 157279 = 157368
- 97 + 157271 = 157368
Showing the first eight; more decompositions exist.
