Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977784, here are decompositions:
- 23 + 977761 = 977784
- 37 + 977747 = 977784
- 61 + 977723 = 977784
- 103 + 977681 = 977784
- 113 + 977671 = 977784
- 173 + 977611 = 977784
- 191 + 977593 = 977784
- 193 + 977591 = 977784
Showing the first eight; more decompositions exist.
