Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78558, here are decompositions:
- 5 + 78553 = 78558
- 17 + 78541 = 78558
- 19 + 78539 = 78558
- 41 + 78517 = 78558
- 47 + 78511 = 78558
- 61 + 78497 = 78558
- 71 + 78487 = 78558
- 79 + 78479 = 78558
Showing the first eight; more decompositions exist.
