Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 129046, here are decompositions:
- 23 + 129023 = 129046
- 53 + 128993 = 129046
- 59 + 128987 = 129046
- 107 + 128939 = 129046
- 167 + 128879 = 129046
- 173 + 128873 = 129046
- 227 + 128819 = 129046
- 233 + 128813 = 129046
Showing the first eight; more decompositions exist.
