Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157288, here are decompositions:
- 11 + 157277 = 157288
- 17 + 157271 = 157288
- 29 + 157259 = 157288
- 41 + 157247 = 157288
- 59 + 157229 = 157288
- 71 + 157217 = 157288
- 107 + 157181 = 157288
- 179 + 157109 = 157288
Showing the first eight; more decompositions exist.
