Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27842, here are decompositions:
- 19 + 27823 = 27842
- 43 + 27799 = 27842
- 79 + 27763 = 27842
- 103 + 27739 = 27842
- 109 + 27733 = 27842
- 151 + 27691 = 27842
- 211 + 27631 = 27842
- 313 + 27529 = 27842
Showing the first eight; more decompositions exist.
