Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43190, here are decompositions:
- 13 + 43177 = 43190
- 31 + 43159 = 43190
- 73 + 43117 = 43190
- 97 + 43093 = 43190
- 127 + 43063 = 43190
- 139 + 43051 = 43190
- 211 + 42979 = 43190
- 223 + 42967 = 43190
Showing the first eight; more decompositions exist.
