Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91438, here are decompositions:
- 5 + 91433 = 91438
- 41 + 91397 = 91438
- 71 + 91367 = 91438
- 107 + 91331 = 91438
- 239 + 91199 = 91438
- 311 + 91127 = 91438
- 317 + 91121 = 91438
- 359 + 91079 = 91438
Showing the first eight; more decompositions exist.
