Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971816, here are decompositions:
- 173 + 4294971643 = 4294971816
- 313 + 4294971503 = 4294971816
- 347 + 4294971469 = 4294971816
- 439 + 4294971377 = 4294971816
- 449 + 4294971367 = 4294971816
- 467 + 4294971349 = 4294971816
- 547 + 4294971269 = 4294971816
- 607 + 4294971209 = 4294971816
Showing the first eight; more decompositions exist.
