Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971902, here are decompositions:
- 19 + 4294971883 = 4294971902
- 43 + 4294971859 = 4294971902
- 61 + 4294971841 = 4294971902
- 73 + 4294971829 = 4294971902
- 229 + 4294971673 = 4294971902
- 433 + 4294971469 = 4294971902
- 523 + 4294971379 = 4294971902
- 601 + 4294971301 = 4294971902
Showing the first eight; more decompositions exist.
