Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71518, here are decompositions:
- 47 + 71471 = 71518
- 89 + 71429 = 71518
- 107 + 71411 = 71518
- 131 + 71387 = 71518
- 179 + 71339 = 71518
- 191 + 71327 = 71518
- 257 + 71261 = 71518
- 269 + 71249 = 71518
Showing the first eight; more decompositions exist.
