Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51862, here are decompositions:
- 3 + 51859 = 51862
- 23 + 51839 = 51862
- 59 + 51803 = 51862
- 113 + 51749 = 51862
- 149 + 51713 = 51862
- 179 + 51683 = 51862
- 263 + 51599 = 51862
- 269 + 51593 = 51862
Showing the first eight; more decompositions exist.
