Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977920, here are decompositions:
- 23 + 977897 = 977920
- 59 + 977861 = 977920
- 71 + 977849 = 977920
- 89 + 977831 = 977920
- 101 + 977819 = 977920
- 107 + 977813 = 977920
- 173 + 977747 = 977920
- 197 + 977723 = 977920
Showing the first eight; more decompositions exist.
