Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63878, here are decompositions:
- 37 + 63841 = 63878
- 79 + 63799 = 63878
- 97 + 63781 = 63878
- 151 + 63727 = 63878
- 181 + 63697 = 63878
- 211 + 63667 = 63878
- 229 + 63649 = 63878
- 271 + 63607 = 63878
Showing the first eight; more decompositions exist.
