Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978620, here are decompositions:
- 3 + 978617 = 978620
- 79 + 978541 = 978620
- 109 + 978511 = 978620
- 157 + 978463 = 978620
- 163 + 978457 = 978620
- 193 + 978427 = 978620
- 271 + 978349 = 978620
- 277 + 978343 = 978620
Showing the first eight; more decompositions exist.
