Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40102, here are decompositions:
- 3 + 40099 = 40102
- 71 + 40031 = 40102
- 89 + 40013 = 40102
- 113 + 39989 = 40102
- 131 + 39971 = 40102
- 149 + 39953 = 40102
- 173 + 39929 = 40102
- 233 + 39869 = 40102
Showing the first eight; more decompositions exist.
