Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78228, here are decompositions:
- 37 + 78191 = 78228
- 61 + 78167 = 78228
- 71 + 78157 = 78228
- 89 + 78139 = 78228
- 107 + 78121 = 78228
- 127 + 78101 = 78228
- 149 + 78079 = 78228
- 179 + 78049 = 78228
Showing the first eight; more decompositions exist.
