Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77564, here are decompositions:
- 7 + 77557 = 77564
- 13 + 77551 = 77564
- 37 + 77527 = 77564
- 43 + 77521 = 77564
- 73 + 77491 = 77564
- 181 + 77383 = 77564
- 241 + 77323 = 77564
- 373 + 77191 = 77564
Showing the first eight; more decompositions exist.
