Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78488, here are decompositions:
- 61 + 78427 = 78488
- 181 + 78307 = 78488
- 211 + 78277 = 78488
- 229 + 78259 = 78488
- 331 + 78157 = 78488
- 349 + 78139 = 78488
- 367 + 78121 = 78488
- 409 + 78079 = 78488
Showing the first eight; more decompositions exist.
