Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27818, here are decompositions:
- 19 + 27799 = 27818
- 67 + 27751 = 27818
- 79 + 27739 = 27818
- 127 + 27691 = 27818
- 277 + 27541 = 27818
- 331 + 27487 = 27818
- 337 + 27481 = 27818
- 409 + 27409 = 27818
Showing the first eight; more decompositions exist.
