Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18862, here are decompositions:
- 3 + 18859 = 18862
- 23 + 18839 = 18862
- 59 + 18803 = 18862
- 89 + 18773 = 18862
- 113 + 18749 = 18862
- 131 + 18731 = 18862
- 149 + 18713 = 18862
- 191 + 18671 = 18862
Showing the first eight; more decompositions exist.
