Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99420, here are decompositions:
- 11 + 99409 = 99420
- 19 + 99401 = 99420
- 23 + 99397 = 99420
- 29 + 99391 = 99420
- 43 + 99377 = 99420
- 53 + 99367 = 99420
- 71 + 99349 = 99420
- 73 + 99347 = 99420
Showing the first eight; more decompositions exist.
