Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56542, here are decompositions:
- 11 + 56531 = 56542
- 23 + 56519 = 56542
- 41 + 56501 = 56542
- 53 + 56489 = 56542
- 89 + 56453 = 56542
- 149 + 56393 = 56542
- 173 + 56369 = 56542
- 293 + 56249 = 56542
Showing the first eight; more decompositions exist.
