Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78636, here are decompositions:
- 13 + 78623 = 78636
- 29 + 78607 = 78636
- 43 + 78593 = 78636
- 53 + 78583 = 78636
- 59 + 78577 = 78636
- 67 + 78569 = 78636
- 83 + 78553 = 78636
- 97 + 78539 = 78636
Showing the first eight; more decompositions exist.
