Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25380, here are decompositions:
- 7 + 25373 = 25380
- 13 + 25367 = 25380
- 23 + 25357 = 25380
- 31 + 25349 = 25380
- 37 + 25343 = 25380
- 41 + 25339 = 25380
- 59 + 25321 = 25380
- 71 + 25309 = 25380
Showing the first eight; more decompositions exist.
