Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78204, here are decompositions:
- 11 + 78193 = 78204
- 13 + 78191 = 78204
- 31 + 78173 = 78204
- 37 + 78167 = 78204
- 41 + 78163 = 78204
- 47 + 78157 = 78204
- 67 + 78137 = 78204
- 83 + 78121 = 78204
Showing the first eight; more decompositions exist.
