Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977740, here are decompositions:
- 17 + 977723 = 977740
- 47 + 977693 = 977740
- 59 + 977681 = 977740
- 131 + 977609 = 977740
- 149 + 977591 = 977740
- 173 + 977567 = 977740
- 227 + 977513 = 977740
- 233 + 977507 = 977740
Showing the first eight; more decompositions exist.
