Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43220, here are decompositions:
- 13 + 43207 = 43220
- 19 + 43201 = 43220
- 31 + 43189 = 43220
- 43 + 43177 = 43220
- 61 + 43159 = 43220
- 103 + 43117 = 43220
- 127 + 43093 = 43220
- 157 + 43063 = 43220
Showing the first eight; more decompositions exist.
