Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84840, here are decompositions:
- 13 + 84827 = 84840
- 29 + 84811 = 84840
- 31 + 84809 = 84840
- 47 + 84793 = 84840
- 53 + 84787 = 84840
- 79 + 84761 = 84840
- 89 + 84751 = 84840
- 103 + 84737 = 84840
Showing the first eight; more decompositions exist.
