Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84272, here are decompositions:
- 43 + 84229 = 84272
- 61 + 84211 = 84272
- 73 + 84199 = 84272
- 109 + 84163 = 84272
- 151 + 84121 = 84272
- 211 + 84061 = 84272
- 439 + 83833 = 84272
- 499 + 83773 = 84272
Showing the first eight; more decompositions exist.
