Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80398, here are decompositions:
- 11 + 80387 = 80398
- 29 + 80369 = 80398
- 89 + 80309 = 80398
- 167 + 80231 = 80398
- 191 + 80207 = 80398
- 251 + 80147 = 80398
- 257 + 80141 = 80398
- 347 + 80051 = 80398
Showing the first eight; more decompositions exist.
