Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78188, here are decompositions:
- 31 + 78157 = 78188
- 67 + 78121 = 78188
- 109 + 78079 = 78188
- 139 + 78049 = 78188
- 157 + 78031 = 78188
- 181 + 78007 = 78188
- 211 + 77977 = 78188
- 349 + 77839 = 78188
Showing the first eight; more decompositions exist.
