Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971878, here are decompositions:
- 19 + 4294971859 = 4294971878
- 37 + 4294971841 = 4294971878
- 97 + 4294971781 = 4294971878
- 271 + 4294971607 = 4294971878
- 409 + 4294971469 = 4294971878
- 487 + 4294971391 = 4294971878
- 499 + 4294971379 = 4294971878
- 577 + 4294971301 = 4294971878
Showing the first eight; more decompositions exist.
