Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90420, here are decompositions:
- 13 + 90407 = 90420
- 17 + 90403 = 90420
- 19 + 90401 = 90420
- 23 + 90397 = 90420
- 41 + 90379 = 90420
- 47 + 90373 = 90420
- 61 + 90359 = 90420
- 67 + 90353 = 90420
Showing the first eight; more decompositions exist.
