Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971388, here are decompositions:
- 11 + 4294971377 = 4294971388
- 167 + 4294971221 = 4294971388
- 179 + 4294971209 = 4294971388
- 311 + 4294971077 = 4294971388
- 479 + 4294970909 = 4294971388
- 509 + 4294970879 = 4294971388
- 569 + 4294970819 = 4294971388
- 821 + 4294970567 = 4294971388
Showing the first eight; more decompositions exist.
