Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977976, here are decompositions:
- 5 + 977971 = 977976
- 53 + 977923 = 977976
- 79 + 977897 = 977976
- 127 + 977849 = 977976
- 157 + 977819 = 977976
- 163 + 977813 = 977976
- 173 + 977803 = 977976
- 229 + 977747 = 977976
Showing the first eight; more decompositions exist.
