Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971986, here are decompositions:
- 43 + 4294971943 = 4294971986
- 103 + 4294971883 = 4294971986
- 127 + 4294971859 = 4294971986
- 157 + 4294971829 = 4294971986
- 313 + 4294971673 = 4294971986
- 379 + 4294971607 = 4294971986
- 607 + 4294971379 = 4294971986
- 619 + 4294971367 = 4294971986
Showing the first eight; more decompositions exist.
