Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69420, here are decompositions:
- 17 + 69403 = 69420
- 19 + 69401 = 69420
- 31 + 69389 = 69420
- 37 + 69383 = 69420
- 41 + 69379 = 69420
- 79 + 69341 = 69420
- 83 + 69337 = 69420
- 103 + 69317 = 69420
Showing the first eight; more decompositions exist.
