Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72906, here are decompositions:
- 5 + 72901 = 72906
- 13 + 72893 = 72906
- 17 + 72889 = 72906
- 23 + 72883 = 72906
- 37 + 72869 = 72906
- 47 + 72859 = 72906
- 83 + 72823 = 72906
- 89 + 72817 = 72906
Showing the first eight; more decompositions exist.
