Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40090, here are decompositions:
- 3 + 40087 = 40090
- 53 + 40037 = 40090
- 59 + 40031 = 40090
- 101 + 39989 = 40090
- 107 + 39983 = 40090
- 137 + 39953 = 40090
- 227 + 39863 = 40090
- 233 + 39857 = 40090
Showing the first eight; more decompositions exist.
