Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91478, here are decompositions:
- 19 + 91459 = 91478
- 67 + 91411 = 91478
- 97 + 91381 = 91478
- 109 + 91369 = 91478
- 181 + 91297 = 91478
- 229 + 91249 = 91478
- 241 + 91237 = 91478
- 337 + 91141 = 91478
Showing the first eight; more decompositions exist.
