Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82380, here are decompositions:
- 7 + 82373 = 82380
- 19 + 82361 = 82380
- 29 + 82351 = 82380
- 31 + 82349 = 82380
- 41 + 82339 = 82380
- 73 + 82307 = 82380
- 79 + 82301 = 82380
- 101 + 82279 = 82380
Showing the first eight; more decompositions exist.
