Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978908, here are decompositions:
- 37 + 978871 = 978908
- 109 + 978799 = 978908
- 181 + 978727 = 978908
- 211 + 978697 = 978908
- 367 + 978541 = 978908
- 397 + 978511 = 978908
- 571 + 978337 = 978908
- 631 + 978277 = 978908
Showing the first eight; more decompositions exist.
