Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8542, here are decompositions:
- 3 + 8539 = 8542
- 5 + 8537 = 8542
- 29 + 8513 = 8542
- 41 + 8501 = 8542
- 113 + 8429 = 8542
- 173 + 8369 = 8542
- 179 + 8363 = 8542
- 251 + 8291 = 8542
Showing the first eight; more decompositions exist.
