Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78194, here are decompositions:
- 3 + 78191 = 78194
- 31 + 78163 = 78194
- 37 + 78157 = 78194
- 73 + 78121 = 78194
- 163 + 78031 = 78194
- 211 + 77983 = 78194
- 331 + 77863 = 78194
- 397 + 77797 = 78194
Showing the first eight; more decompositions exist.
