Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85288, here are decompositions:
- 29 + 85259 = 85288
- 41 + 85247 = 85288
- 59 + 85229 = 85288
- 89 + 85199 = 85288
- 167 + 85121 = 85288
- 179 + 85109 = 85288
- 197 + 85091 = 85288
- 227 + 85061 = 85288
Showing the first eight; more decompositions exist.
