Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18802, here are decompositions:
- 5 + 18797 = 18802
- 29 + 18773 = 18802
- 53 + 18749 = 18802
- 59 + 18743 = 18802
- 71 + 18731 = 18802
- 83 + 18719 = 18802
- 89 + 18713 = 18802
- 101 + 18701 = 18802
Showing the first eight; more decompositions exist.
