Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39420, here are decompositions:
- 11 + 39409 = 39420
- 23 + 39397 = 39420
- 37 + 39383 = 39420
- 47 + 39373 = 39420
- 53 + 39367 = 39420
- 61 + 39359 = 39420
- 79 + 39341 = 39420
- 97 + 39323 = 39420
Showing the first eight; more decompositions exist.
