Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 112542, here are decompositions:
- 41 + 112501 = 112542
- 61 + 112481 = 112542
- 83 + 112459 = 112542
- 113 + 112429 = 112542
- 139 + 112403 = 112542
- 179 + 112363 = 112542
- 181 + 112361 = 112542
- 193 + 112349 = 112542
Showing the first eight; more decompositions exist.
