Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971778, here are decompositions:
- 281 + 4294971497 = 4294971778
- 347 + 4294971431 = 4294971778
- 389 + 4294971389 = 4294971778
- 401 + 4294971377 = 4294971778
- 509 + 4294971269 = 4294971778
- 557 + 4294971221 = 4294971778
- 569 + 4294971209 = 4294971778
- 677 + 4294971101 = 4294971778
Showing the first eight; more decompositions exist.
