Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56142, here are decompositions:
- 11 + 56131 = 56142
- 19 + 56123 = 56142
- 29 + 56113 = 56142
- 41 + 56101 = 56142
- 43 + 56099 = 56142
- 61 + 56081 = 56142
- 89 + 56053 = 56142
- 101 + 56041 = 56142
Showing the first eight; more decompositions exist.
