Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27590, here are decompositions:
- 7 + 27583 = 27590
- 61 + 27529 = 27590
- 103 + 27487 = 27590
- 109 + 27481 = 27590
- 163 + 27427 = 27590
- 181 + 27409 = 27590
- 193 + 27397 = 27590
- 223 + 27367 = 27590
Showing the first eight; more decompositions exist.
