Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78648, here are decompositions:
- 5 + 78643 = 78648
- 41 + 78607 = 78648
- 71 + 78577 = 78648
- 79 + 78569 = 78648
- 107 + 78541 = 78648
- 109 + 78539 = 78648
- 131 + 78517 = 78648
- 137 + 78511 = 78648
Showing the first eight; more decompositions exist.
