Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77984, here are decompositions:
- 7 + 77977 = 77984
- 211 + 77773 = 77984
- 223 + 77761 = 77984
- 241 + 77743 = 77984
- 271 + 77713 = 77984
- 337 + 77647 = 77984
- 367 + 77617 = 77984
- 373 + 77611 = 77984
Showing the first eight; more decompositions exist.
