Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78564, here are decompositions:
- 11 + 78553 = 78564
- 23 + 78541 = 78564
- 47 + 78517 = 78564
- 53 + 78511 = 78564
- 67 + 78497 = 78564
- 97 + 78467 = 78564
- 127 + 78437 = 78564
- 137 + 78427 = 78564
Showing the first eight; more decompositions exist.
