Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157318, here are decompositions:
- 11 + 157307 = 157318
- 41 + 157277 = 157318
- 47 + 157271 = 157318
- 59 + 157259 = 157318
- 71 + 157247 = 157318
- 89 + 157229 = 157318
- 101 + 157217 = 157318
- 107 + 157211 = 157318
Showing the first eight; more decompositions exist.
