Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79380, here are decompositions:
- 13 + 79367 = 79380
- 23 + 79357 = 79380
- 31 + 79349 = 79380
- 43 + 79337 = 79380
- 47 + 79333 = 79380
- 61 + 79319 = 79380
- 71 + 79309 = 79380
- 79 + 79301 = 79380
Showing the first eight; more decompositions exist.
