Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71370, here are decompositions:
- 7 + 71363 = 71370
- 11 + 71359 = 71370
- 17 + 71353 = 71370
- 23 + 71347 = 71370
- 29 + 71341 = 71370
- 31 + 71339 = 71370
- 37 + 71333 = 71370
- 41 + 71329 = 71370
Showing the first eight; more decompositions exist.
