Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40830, here are decompositions:
- 7 + 40823 = 40830
- 11 + 40819 = 40830
- 17 + 40813 = 40830
- 29 + 40801 = 40830
- 43 + 40787 = 40830
- 59 + 40771 = 40830
- 67 + 40763 = 40830
- 71 + 40759 = 40830
Showing the first eight; more decompositions exist.
