Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77684, here are decompositions:
- 3 + 77681 = 77684
- 37 + 77647 = 77684
- 43 + 77641 = 77684
- 67 + 77617 = 77684
- 73 + 77611 = 77684
- 97 + 77587 = 77684
- 127 + 77557 = 77684
- 157 + 77527 = 77684
Showing the first eight; more decompositions exist.
