Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84780, here are decompositions:
- 19 + 84761 = 84780
- 29 + 84751 = 84780
- 43 + 84737 = 84780
- 61 + 84719 = 84780
- 67 + 84713 = 84780
- 79 + 84701 = 84780
- 83 + 84697 = 84780
- 89 + 84691 = 84780
Showing the first eight; more decompositions exist.
