Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971872, here are decompositions:
- 13 + 4294971859 = 4294971872
- 31 + 4294971841 = 4294971872
- 43 + 4294971829 = 4294971872
- 199 + 4294971673 = 4294971872
- 229 + 4294971643 = 4294971872
- 523 + 4294971349 = 4294971872
- 571 + 4294971301 = 4294971872
- 673 + 4294971199 = 4294971872
Showing the first eight; more decompositions exist.
