Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78124, here are decompositions:
- 3 + 78121 = 78124
- 23 + 78101 = 78124
- 83 + 78041 = 78124
- 107 + 78017 = 78124
- 173 + 77951 = 78124
- 191 + 77933 = 78124
- 257 + 77867 = 78124
- 311 + 77813 = 78124
Showing the first eight; more decompositions exist.
