Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78230, here are decompositions:
- 37 + 78193 = 78230
- 67 + 78163 = 78230
- 73 + 78157 = 78230
- 109 + 78121 = 78230
- 151 + 78079 = 78230
- 181 + 78049 = 78230
- 199 + 78031 = 78230
- 223 + 78007 = 78230
Showing the first eight; more decompositions exist.
