Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78830, here are decompositions:
- 7 + 78823 = 78830
- 43 + 78787 = 78830
- 109 + 78721 = 78830
- 139 + 78691 = 78830
- 181 + 78649 = 78830
- 223 + 78607 = 78830
- 277 + 78553 = 78830
- 313 + 78517 = 78830
Showing the first eight; more decompositions exist.
