Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971742, here are decompositions:
- 179 + 4294971563 = 4294971742
- 239 + 4294971503 = 4294971742
- 251 + 4294971491 = 4294971742
- 311 + 4294971431 = 4294971742
- 353 + 4294971389 = 4294971742
- 419 + 4294971323 = 4294971742
- 521 + 4294971221 = 4294971742
- 641 + 4294971101 = 4294971742
Showing the first eight; more decompositions exist.
