Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84420, here are decompositions:
- 13 + 84407 = 84420
- 19 + 84401 = 84420
- 29 + 84391 = 84420
- 31 + 84389 = 84420
- 43 + 84377 = 84420
- 71 + 84349 = 84420
- 73 + 84347 = 84420
- 101 + 84319 = 84420
Showing the first eight; more decompositions exist.
