Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78180, here are decompositions:
- 7 + 78173 = 78180
- 13 + 78167 = 78180
- 17 + 78163 = 78180
- 23 + 78157 = 78180
- 41 + 78139 = 78180
- 43 + 78137 = 78180
- 59 + 78121 = 78180
- 79 + 78101 = 78180
Showing the first eight; more decompositions exist.
