Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78132, here are decompositions:
- 11 + 78121 = 78132
- 31 + 78101 = 78132
- 53 + 78079 = 78132
- 73 + 78059 = 78132
- 83 + 78049 = 78132
- 101 + 78031 = 78132
- 149 + 77983 = 78132
- 163 + 77969 = 78132
Showing the first eight; more decompositions exist.
