Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971642, here are decompositions:
- 79 + 4294971563 = 4294971642
- 139 + 4294971503 = 4294971642
- 151 + 4294971491 = 4294971642
- 173 + 4294971469 = 4294971642
- 211 + 4294971431 = 4294971642
- 251 + 4294971391 = 4294971642
- 263 + 4294971379 = 4294971642
- 293 + 4294971349 = 4294971642
Showing the first eight; more decompositions exist.
