Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85488, here are decompositions:
- 19 + 85469 = 85488
- 37 + 85451 = 85488
- 41 + 85447 = 85488
- 59 + 85429 = 85488
- 61 + 85427 = 85488
- 107 + 85381 = 85488
- 127 + 85361 = 85488
- 157 + 85331 = 85488
Showing the first eight; more decompositions exist.
