Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157308, here are decompositions:
- 5 + 157303 = 157308
- 17 + 157291 = 157308
- 29 + 157279 = 157308
- 31 + 157277 = 157308
- 37 + 157271 = 157308
- 61 + 157247 = 157308
- 79 + 157229 = 157308
- 89 + 157219 = 157308
Showing the first eight; more decompositions exist.
