Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43280, here are decompositions:
- 19 + 43261 = 43280
- 43 + 43237 = 43280
- 73 + 43207 = 43280
- 79 + 43201 = 43280
- 103 + 43177 = 43280
- 163 + 43117 = 43280
- 229 + 43051 = 43280
- 277 + 43003 = 43280
Showing the first eight; more decompositions exist.
