Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43130, here are decompositions:
- 13 + 43117 = 43130
- 37 + 43093 = 43130
- 67 + 43063 = 43130
- 79 + 43051 = 43130
- 127 + 43003 = 43130
- 151 + 42979 = 43130
- 163 + 42967 = 43130
- 193 + 42937 = 43130
Showing the first eight; more decompositions exist.
