Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55808, here are decompositions:
- 97 + 55711 = 55808
- 127 + 55681 = 55808
- 199 + 55609 = 55808
- 229 + 55579 = 55808
- 307 + 55501 = 55808
- 367 + 55441 = 55808
- 397 + 55411 = 55808
- 409 + 55399 = 55808
Showing the first eight; more decompositions exist.
