Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82542, here are decompositions:
- 11 + 82531 = 82542
- 13 + 82529 = 82542
- 43 + 82499 = 82542
- 59 + 82483 = 82542
- 71 + 82471 = 82542
- 73 + 82469 = 82542
- 79 + 82463 = 82542
- 149 + 82393 = 82542
Showing the first eight; more decompositions exist.
