Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80356, here are decompositions:
- 47 + 80309 = 80356
- 83 + 80273 = 80356
- 149 + 80207 = 80356
- 179 + 80177 = 80356
- 317 + 80039 = 80356
- 359 + 79997 = 80356
- 383 + 79973 = 80356
- 389 + 79967 = 80356
Showing the first eight; more decompositions exist.
