Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 41820, here are decompositions:
- 7 + 41813 = 41820
- 11 + 41809 = 41820
- 19 + 41801 = 41820
- 43 + 41777 = 41820
- 59 + 41761 = 41820
- 61 + 41759 = 41820
- 83 + 41737 = 41820
- 101 + 41719 = 41820
Showing the first eight; more decompositions exist.
