Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163542, here are decompositions:
- 59 + 163483 = 163542
- 61 + 163481 = 163542
- 73 + 163469 = 163542
- 109 + 163433 = 163542
- 131 + 163411 = 163542
- 139 + 163403 = 163542
- 149 + 163393 = 163542
- 179 + 163363 = 163542
Showing the first eight; more decompositions exist.
