Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8538, here are decompositions:
- 11 + 8527 = 8538
- 17 + 8521 = 8538
- 37 + 8501 = 8538
- 71 + 8467 = 8538
- 107 + 8431 = 8538
- 109 + 8429 = 8538
- 149 + 8389 = 8538
- 151 + 8387 = 8538
Showing the first eight; more decompositions exist.
