Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78224, here are decompositions:
- 31 + 78193 = 78224
- 61 + 78163 = 78224
- 67 + 78157 = 78224
- 103 + 78121 = 78224
- 193 + 78031 = 78224
- 241 + 77983 = 78224
- 331 + 77893 = 78224
- 463 + 77761 = 78224
Showing the first eight; more decompositions exist.
