Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85438, here are decompositions:
- 11 + 85427 = 85438
- 107 + 85331 = 85438
- 179 + 85259 = 85438
- 191 + 85247 = 85438
- 239 + 85199 = 85438
- 317 + 85121 = 85438
- 347 + 85091 = 85438
- 389 + 85049 = 85438
Showing the first eight; more decompositions exist.
