Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71238, here are decompositions:
- 5 + 71233 = 71238
- 29 + 71209 = 71238
- 47 + 71191 = 71238
- 67 + 71171 = 71238
- 71 + 71167 = 71238
- 109 + 71129 = 71238
- 149 + 71089 = 71238
- 157 + 71081 = 71238
Showing the first eight; more decompositions exist.
