Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43020, here are decompositions:
- 7 + 43013 = 43020
- 17 + 43003 = 43020
- 31 + 42989 = 43020
- 41 + 42979 = 43020
- 53 + 42967 = 43020
- 59 + 42961 = 43020
- 67 + 42953 = 43020
- 83 + 42937 = 43020
Showing the first eight; more decompositions exist.
