Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78164, here are decompositions:
- 7 + 78157 = 78164
- 43 + 78121 = 78164
- 157 + 78007 = 78164
- 181 + 77983 = 78164
- 271 + 77893 = 78164
- 367 + 77797 = 78164
- 421 + 77743 = 78164
- 433 + 77731 = 78164
Showing the first eight; more decompositions exist.
