Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78222, here are decompositions:
- 19 + 78203 = 78222
- 29 + 78193 = 78222
- 31 + 78191 = 78222
- 43 + 78179 = 78222
- 59 + 78163 = 78222
- 83 + 78139 = 78222
- 101 + 78121 = 78222
- 163 + 78059 = 78222
Showing the first eight; more decompositions exist.
