Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78622, here are decompositions:
- 29 + 78593 = 78622
- 53 + 78569 = 78622
- 83 + 78539 = 78622
- 113 + 78509 = 78622
- 281 + 78341 = 78622
- 311 + 78311 = 78622
- 389 + 78233 = 78622
- 419 + 78203 = 78622
Showing the first eight; more decompositions exist.
