Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971856, here are decompositions:
- 293 + 4294971563 = 4294971856
- 353 + 4294971503 = 4294971856
- 359 + 4294971497 = 4294971856
- 467 + 4294971389 = 4294971856
- 479 + 4294971377 = 4294971856
- 587 + 4294971269 = 4294971856
- 647 + 4294971209 = 4294971856
- 797 + 4294971059 = 4294971856
Showing the first eight; more decompositions exist.
