Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17390, here are decompositions:
- 3 + 17387 = 17390
- 7 + 17383 = 17390
- 13 + 17377 = 17390
- 31 + 17359 = 17390
- 73 + 17317 = 17390
- 97 + 17293 = 17390
- 151 + 17239 = 17390
- 181 + 17209 = 17390
Showing the first eight; more decompositions exist.
