Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39390, here are decompositions:
- 7 + 39383 = 39390
- 17 + 39373 = 39390
- 19 + 39371 = 39390
- 23 + 39367 = 39390
- 31 + 39359 = 39390
- 47 + 39343 = 39390
- 67 + 39323 = 39390
- 73 + 39317 = 39390
Showing the first eight; more decompositions exist.
