Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294962942, here are decompositions:
- 13 + 4294962929 = 4294962942
- 31 + 4294962911 = 4294962942
- 43 + 4294962899 = 4294962942
- 89 + 4294962853 = 4294962942
- 163 + 4294962779 = 4294962942
- 191 + 4294962751 = 4294962942
- 211 + 4294962731 = 4294962942
- 223 + 4294962719 = 4294962942
Showing the first eight; more decompositions exist.
