Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85408, here are decompositions:
- 47 + 85361 = 85408
- 149 + 85259 = 85408
- 179 + 85229 = 85408
- 317 + 85091 = 85408
- 347 + 85061 = 85408
- 359 + 85049 = 85408
- 431 + 84977 = 85408
- 461 + 84947 = 85408
Showing the first eight; more decompositions exist.
