Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63840, here are decompositions:
- 17 + 63823 = 63840
- 31 + 63809 = 63840
- 37 + 63803 = 63840
- 41 + 63799 = 63840
- 47 + 63793 = 63840
- 59 + 63781 = 63840
- 67 + 63773 = 63840
- 79 + 63761 = 63840
Showing the first eight; more decompositions exist.
