Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977730, here are decompositions:
- 7 + 977723 = 977730
- 11 + 977719 = 977730
- 37 + 977693 = 977730
- 59 + 977671 = 977730
- 101 + 977629 = 977730
- 137 + 977593 = 977730
- 139 + 977591 = 977730
- 163 + 977567 = 977730
Showing the first eight; more decompositions exist.
